Engineered to meet the exact load parameters of Brazilian industrial machinery. High tensile strength, thermal conductivity, and extreme wear defense.
Brazil stands as a global powerhouse in heavy industries. From the expansive open-pit iron ore mines of Pará and Minas Gerais (operated by mining titans like Vale) to the offshore oil fields of the Campos and Santos Basins, the mechanical demands placed on industrial equipment are staggering. Industrial machinery in these sectors operates under extreme loads, high friction, and frequently corrosive environments.
Lead bronze alloys, known for their superior self-lubricating properties, emergency running characteristics, and high resistance to wear, are critical components for the manufacturing of bushings, slide plates, engine bearings, and wear rings. In tropical agricultural machinery—such as the high-capacity sugarcane harvesters operating in São Paulo state—components are subjected to high levels of abrasive soil and moisture. Traditional alloys quickly fail, whereas leaded bronze provides the durability required to prevent catastrophic machine failure and minimize costly operational downtime.
Additionally, Brazil’s rapid modernization of its automotive manufacturing sector and expanding electrical grid infrastructure demands copper alloys with precise metallurgy and consistent wear tolerances. As a leading manufacturer, we provide the engineering depth and materials science required to keep Brazil’s industrial sectors running at peak efficiency.
Established in 2017, Sichuan Kepai New Materials Co., Ltd. is a modern high-tech enterprise integrating research and development, high-precision production, and global sales. Currently, our manufacturing facility covers an area of approximately 9,000 square meters, complemented by a 1,000 square meter administrative and technical office space.
Our core focus lies in the production of strategic emerging new materials, specifically high-performance copper alloys including tellurium copper, lead bronze, high-conductivity oxygen-free copper, silver copper, dispersion copper, and beryllium copper alloys. Our products are applied in forward-looking industries such as new energy vehicles (NEVs), 5G telecommunication arrays, high-power industrial laser cutting, aerospace, and high-voltage lithium battery relays.
Through advanced metallurgical engineering, we provide high-conductivity, easy-to-machine, and high-strength options tailored to meet strict international standards, ensuring that clients in South America and beyond receive premium-grade materials optimized for competitive market environments.
Our laboratory and processing equipment ensure every batch of lead bronze exported to Brazil meets precise chemical composition and physical performance indicators.
Technological innovation is the core competitiveness of Sichuan Kepai New Materials. We have formed a specialized team composed of senior metallurgical experts, mechanical engineers, and quality analysts who continually push the boundaries of copper alloy performance. By integrating continuous casting, heat treatment, and precision cold drawing, we produce lead bronze with a highly uniform distribution of lead particles. This prevents the segregation issues common in lower-tier manufacturing processes, giving our alloys exceptional wear life and predictable physical properties.
Our products are widely utilized in new energy vehicles, precision CNC turned components, plasma cutting torches, electrical switches, and large-scale industrial energy storage. With a market reach extending globally, we actively support Brazilian manufacturers in optimizing their supply chains and lowering total operational costs.
Our complete testing and production workflow includes direct-reading spectrometers, ultrasonic flaw detectors, tensile strength testers, and metallographic microscopes. By strictly controlling the smelting, casting, extrusion, drawing, straightening, and packaging stages, we ensure zero defects. Brazilian customers benefit from our comprehensive quality reports and material traceability, securing their position in a competitive global market.

How Kepai resolves key friction points in the supply chain for South American heavy industry players.
Standard lead bronze processing often suffers from gravity segregation, leading to brittle zones. Our continuous casting technology creates an ultra-fine, highly dispersed lead distribution, ensuring uniform wear resistance and high machinability.
Sea transit to major Brazilian ports (Santos, Paranaguá, Rio de Janeiro) exposes metals to high salinity and moisture. We utilize specialized vacuum sealing, anti-corrosive wraps, and heavy-duty structural packaging to ensure products arrive clean and pristine.
Reduce material waste and machining time. We export pre-straightened rods, hollow tubes, and custom profile sections aligned with ABNT NBR standards, allowing immediate fabrication upon receipt at your factory.

Send Inquiry NowExporting industrial metals to Brazil requires a thorough understanding of local regulatory frameworks.四川吉派 (Kepai) ensures all export procedures align with Siscomex (Brazil's integrated foreign trade system) guidelines, minimizing customs clearance delays. We provide full documentation packages, including SGS reports, Mill Test Certificates (MTC) matching EN 10204 3.1, and detailed packing list specifications.
Our products are engineered to conform to ABNT NBR standards for copper alloys, as well as ASTM B505 and ASTM B271 specifications. For enterprises prioritizing ecological compliance, we assist in establishing sustainable sourcing protocols. Since lead is a restricted substance under various international regulations, we offer precise chemical analysis certificates, detailing lead concentrations down to PPM (parts per million), allowing you to comply with RoHS regulations and corporate sustainability targets.
We work closely with local Brazilian distributors, logistics brokers, and industrial purchasing networks in São Paulo, Belo Horizonte, and Porto Alegre. Our support system is designed to provide rapid responses to technical inquiries, fast quotation generation, and flexible payment terms for qualifying corporate buyers.
Our commitment to excellence is validated by international auditing bodies, assuring high reliability for critical operations.
