As a premier Custom Aluminum Bronze Factory & Exporter, we recognize that modern engineering demands more than just basic materials. In the current industrial landscape, Aluminum Bronze (CuAl alloys) has emerged as the gold standard for high-stress, corrosive environments. Unlike standard brass or commercial bronzes, Aluminum Bronze offers a unique combination of high strength, excellent corrosion resistance (especially in seawater), and superior wear resistance.
The formation of a tenacious, self-healing protective oxide layer (Alumina) makes our custom aluminum bronze the preferred choice for marine hardware, subsea valves, and offshore oil and gas components. This "passive film" provides resistance that outperforms stainless steel in many chloride-rich environments.
With tensile strengths comparable to medium carbon steels, our alloys such as C63000 (Nickel Aluminum Bronze) and C95400 provide the structural rigidity needed for heavy-duty bushings, landing gear components, and high-load wear plates.
Retaining its properties at elevated temperatures, Aluminum Bronze is vital for heat exchanger components and boiler parts. Our factory utilizes vacuum induction melting to ensure metallurgical purity, providing Information Gain for engineers seeking predictable lifecycle performance.
Established in 2017, Sichuan Kepai is a high-tech enterprise integrating R&D, production, and sales. With a 9,000 square meter facility and specialized expertise in strategic emerging new materials, we are at the forefront of China's "13th Five-Year Plan" for material science. Our focus extends to special copper alloys including tellurium copper, high-conductivity oxygen-free copper, and dispersion copper.
Strategic Sourcing for the Global Enterprise
China-based factories like Kepai benefit from a centralized supply chain, reducing lead times for custom smelting, extrusion, and CNC machining. We offer a "One-Stop" solution from raw ingot to finished precision part.
Through advanced automation and large-scale extrusion (up to 2500T), we provide high-specification Aluminum Bronze at a significant cost advantage without compromising on ASTM, DIN, or JIS standards.
Our focus on New Energy Vehicles (EV) and 5G technology has led to the development of proprietary alloys that meet the thermal and conductivity needs of the next generation of infrastructure.
Localized Application Scenarios & Global Demand
Aluminum bronze is non-sparking and biofouling resistant. Application: Propeller shafts, pump internal components, and desalination system fasteners.
Used for landing gear bushings and sleeve bearings where heavy loads and friction would cause other metals to gall or seize.
Wear strips and guide rails in stamping presses and plastic injection molding machines require the extreme hardness of C95400 alloys.
Specialized copper alloys developed for lithium battery relays, ensuring high conductivity and mechanical reliability in EV power systems.

Sustainability and Technical Evolution
The global copper alloy industry is shifting towards High-Conductivity, High-Strength, and Easy-to-Machine materials. Sichuan Kepai is leading this transition by developing lead-free alternatives that maintain superior machinability. As an exporter, we see a growing demand for Circular Economy practices, where the longevity of aluminum bronze components reduces the frequency of replacements, lowering the total carbon footprint of heavy industrial projects.
Our market layout follows a strategy of "Rooted in Sichuan, radiating nationwide, and moving towards the world." This ensures that whether you are a buyer in Europe or North America, our logistics and quality certification (ISO) meet your stringent procurement protocols.
