Engineered for extreme reliability, our primary copper products satisfy strict international tolerances for Peruvian mining and industrial standards.
As one of the world's leading mineral economies, Peru represents a critical hub for global metallurgical supply chains. However, the domestic Peruvian market is undergoing a rapid evolution. The national focus is shifting from raw ore extraction to high-value-added industrial components. Sectors such as electrical power transmission, high-capacity underground mining infrastructure, and renewable energy installations (including extensive solar arrays in the southern deserts of Arequipa and Moquegua) require ultra-pure, high-conductivity copper materials that meet stringent mechanical and chemical thresholds.
To support this high-altitude grid resilience, our supply chain provides specialized oxygen-free high-conductivity (OFHC) copper and advanced copper alloys. By minimizing interstitial oxygen and other volatile impurities, our materials guarantee high structural integrity, protecting infrastructure from hydrogen-induced embrittlement and fatigue under cyclic loading conditions.

Modern electrical infrastructure is scaling to support high-voltage direct current (HVDC) transmission lines across the Andes and into urban centers like Lima. To support this growth, our metallurgical research team is developing new processing techniques for pure copper and high-conductivity copper alloys. The transition to higher efficiency networks requires managing grain structure orientation during the extrusion and drawing phases.
Our research and development program focuses on trace-element optimization. By introducing controlled trace additions of silver (Ag) or tellurium (Te) to the copper matrix, we can increase the softening temperature of the copper without reducing its electrical conductivity. This approach is highly valuable for high-speed automated CNC machining and precision contact tips used in plasma and laser cutting equipment throughout Peru's metal fabrication shops.
Additionally, we are focused on the development of chromium-zirconium-copper (CuCr1Zr) alloys. These materials are designed to resist thermal deformation in resistance welding and heavy industrial switchgear installations, offering high performance under demanding mechanical stress.
Sichuan Kepai New Materials Co., Ltd. operates a modern, technology-driven manufacturing facility. Established in 2017 in Guanghan, Sichuan, our factory covers 9,000 square meters. It is designed to produce strategic, high-performance copper alloys that support modern industrial applications.
Our production line is monitored with integrated testing systems. Every batch of high-purity copper and specialized alloy undergoes eddy current conductivity testing, chemical composition verification using optical emission spectrometers, and mechanical testing. This ensures full compliance with international standards, including ASTM, EN, and JIS.

Our specialized alloy series are designed to meet requirements for conductivity, corrosion resistance, and machinability across various environments in Peru.
Peruvian industries require materials that can withstand various environmental conditions, from high-salinity coastal areas to cold mountain climates. Our product lines are designed to meet these specific challenges:
The processing of copper and gold ores requires highly reliable machinery. We supply high-strength copper alloys, such as C17200 Beryllium Copper and C17500 Beryllium Cobalt Copper, which offer high mechanical strength alongside electrical conductivity. These materials are used in wear plates, heavy bushing gear, and non-sparking safety tools required in underground mines throughout the Cajamarca and Apurímac regions.
Our C11000 Electrolytic Tough Pitch (ETP) copper plates and bars provide high electrical and thermal conductivity. They are used in power distribution networks, high-voltage switchgear, and substation grounding grids designed to handle seismic movements along the Pacific Ring of Fire.
As Peru increases its solar and wind generation capacity, efficient power transmission is critical. Our ultra-pure oxygen-free copper rods and bars help minimize resistive losses in solar inverters, step-up transformers, and long-distance transmission connections.
We provide comprehensive documentation and certification for our shipments to Peru. Every order is delivered with mill test certificates (MTC) showing the exact chemical composition and physical properties of the material.
Our logistics team coordinates shipping with international carriers, managing sea freight routes from major Chinese ports directly to the Port of Callao. We provide complete documentation support, including Certificates of Origin, Bill of Lading (B/L), packing lists, and commercial invoices to facilitate customs clearance.
Our factory operates under ISO 9001 and ISO 14001 management systems, ensuring consistent production quality and compliance with environmental standards.
Answers to common technical questions regarding copper alloys, international standards, and supply logistics for the Peruvian market.
C11000 Electrolytic Tough Pitch (ETP) copper contains a small amount of controlled oxygen (typically 100 to 400 ppm) to align impurities at grain boundaries, providing an electrical conductivity of 100% to 101% IACS. However, under high-temperature or reducing atmospheres containing hydrogen, ETP copper can suffer from hydrogen embrittlement. Oxygen-Free Copper (such as C10200 or high-purity C10100) has an oxygen content below 10 ppm (and often below 5 ppm). This makes OFC highly resistant to hydrogen embrittlement, improving reliability in high-altitude substation transformers and underground mining equipment where ventilation is limited.
Pure copper is highly ductile, which can cause tool wear and chips that stick during high-speed machining. C14500 Tellurium Copper has a small addition of tellurium (0.4% to 0.7%), which creates fine, dispersed telluride particles in the copper matrix. This increases the free-machining rating to 85% (compared to 20% for pure copper) while maintaining 93% to 98% IACS electrical conductivity. This allows for faster machining speeds, cleaner cuts, and longer tool life when producing components like contact tips, electrical connectors, and switches.
Every shipment includes a Mill Test Certificate (MTC) conforming to EN 10204 3.1. This certificate details the chemical composition (verified by optical emission spectrometry), tensile strength, elongation, hardness, and electrical conductivity (IACS %). We also offer third-party testing reports from international agencies like SGS or TÜV upon request.
Typically, custom manufacturing and processing take 15 to 25 days depending on the size of the order and the specific dimensions requested. Rail or road transport to major export ports (such as Shanghai or Shenzhen) takes 3 to 5 days, followed by ocean freight to Callao (Lima), which takes approximately 30 to 38 days. Our logistics team provides tracking updates throughout the transit process.
We use specialized export packaging to protect the copper during maritime transport. All rods, sheets, and components are wrapped in vapor-corrosion-inhibiting (VCI) paper or film, placed in moisture-barrier bags with desiccants, and packed in reinforced, IPPC-fumigated wooden crates. This packaging prevents exposure to sea air and moisture, ensuring the materials arrive clean and ready for use.

When sourcing high-purity copper and copper alloys for large-scale projects, procurement teams should evaluate several factors beyond base metal pricing:
Using lower-grade copper with higher impurity levels can lead to increased electrical losses, temperature rise in systems, and shorter component lifespans. Investing in high-conductivity materials (such as our 101% IACS certified oxygen-free copper) helps lower operational costs and reduces maintenance requirements over the lifetime of the installation.
Variations in alloy composition can impact machining speed and tool wear. We maintain consistent chemistry across batches through vacuum induction melting and automated spectrometer verification, allowing buyers to maintain stable CNC machining parameters.
