Description

Copper Metal Alloy-Copper Tin is a high-performance metallic alloy composed primarily of copper with tin as a key alloying element. This material is engineered to deliver superior mechanical properties, including enhanced strength, wear resistance, and excellent corrosion protection compared to pure copper. It is a critical component for manufacturers in sectors requiring durable, reliable, and conductive metal parts. Key industries that utilize this alloy include automotive engineering, electrical component manufacturing, industrial bearing production, and specialized machinery.

Application

• Bearing and Bushings: Used in the production of high-load, low-friction bearings and bushings for automotive and industrial machinery due to its excellent wear resistance and embeddability.
• Electrical Contacts and Connectors: Serves as a material for electrical contacts, terminals, and connectors, leveraging its good electrical conductivity and improved mechanical strength.
• Marine and Corrosive Environment Components: Ideal for valves, pump parts, and fittings in marine applications because of its enhanced resistance to corrosion, especially in seawater.
• Gears and Synchronizer Rings: Employed in the manufacturing of gears and synchronizer rings in automotive transmissions, where strength and anti-galling properties are paramount.
• Decorative Hardware and Architectural Fittings: Used for high-quality door handles, locks, and architectural fixtures that require a combination of aesthetic appeal, durability, and corrosion resistance.
• Welding and Brazing Alloys: Acts as a base material in specific welding rods and brazing alloys to join copper-based metals and other materials.

Quality Control

Our Copper-Tin Alloy is produced under strict quality management protocols to ensure batch-to-batch consistency and compliance with international material standards such as ASTM, SAE, and DIN. Each lot is subjected to rigorous analytical testing, including spectroscopic analysis for composition, mechanical property verification, and dimensional checks. A Certificate of Analysis (COA) detailing the specific chemical composition and physical properties is provided with every shipment to guarantee traceability and performance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids. To prevent surface oxidation or tarnishing, it is recommended to store the alloy in a low-humidity environment. Standard warehouse conditions (15-25°C) are typically suitable.
