Introduction

C85800 Solid Copper Rod Round Bar

C85800 copper rod is a high-performance manganese-lead brass. Its balanced and excellent overall performance makes it a key choice for critical industrial components. It not only excels in cutting, with easy chip breakage and a smooth surface finish, significantly improving productivity and tool life, but also combines the high strength and hardness imparted by manganese with exceptional wear resistance, making it suitable for demanding physical environments such as load-bearing, movement, and friction.

Furthermore, this material inherits the excellent corrosion resistance of brass, withstanding erosion from a variety of media, including air and seawater, ensuring long service life in harsh operating conditions such as marine and chemical industries. Therefore, C85800 copper rod is ideal for manufacturing parts requiring both excellent mechanical properties and efficient machinability, such as high-strength nuts, marine pumps and valves, and gear bushings.

Advantages

Advantages of C85800 Solid Copper Rod Round Bar

Excellent machinability and high surface quality

This is its most significant advantage. The lead content in the material ensures fine, easily broken chips during high-speed cutting. This not only significantly reduces tool wear and energy consumption, but also produces a highly precise, smooth machined surface, making it particularly suitable for high-volume automated production.

High Strength, High Hardness, and Excellent Wear Resistance

Thanks to the solid solution strengthening effect of manganese, C85800 exhibits higher strength, hardness, and fatigue resistance than ordinary brass. It can withstand heavy loads and impacts, and is highly wear-resistant, making it suitable for manufacturing parts subject to long-term friction and movement.

Excellent Corrosion Resistance

It inherits the excellent corrosion resistance of brass in air, freshwater, and seawater, making it resistant to a wide range of environments. This advantage ensures long life and reliability in corrosive environments such as shipbuilding, marine engineering, and the chemical industry.

Excellent Balance of Mechanical Properties

In addition to its outstanding individual performance, C85800 excels in its perfect balance of various mechanical properties. It combines high strength, good toughness and certain ductility. It is an engineering material with excellent comprehensive performance and can meet various requirements under complex working conditions.

Applications for C85800 Solid Copper Rod Round Bar

Shipbuilding and Offshore Engineering

C85800 is an ideal material for marine propellers, pump housings, valve components, and seawater piping system components. It resists seawater corrosion, while its high strength and wear resistance are sufficient to withstand the immense water pressure and long-term erosion.

Heavy-Duty Machinery and Wear-Resistant Parts

Due to its high strength and excellent wear resistance, it is often used in the manufacture of bearings, bushings, gears, and high-strength nuts for heavy machinery. These components must operate reliably under high pressure and high friction environments, and C85800's performance perfectly meets these requirements.

Chemical and Fluid Handling Equipment

In the chemical, petroleum, and water supply systems, C85800 is used to manufacture core components, flanges, and filter elements for pumps and valves. Its excellent corrosion resistance allows it to withstand a wide range of chemical media, while its superior machinability ensures precision machining of critical sealing surfaces.

High-Strength Structural Parts and Connectors

In structural applications requiring non-magnetic properties, high strength, and excellent corrosion resistance, C85800 can be used to manufacture connectors for electrical equipment, high-voltage switchgear components, and non-critical load-bearing structural components in aerospace. Its easy-to-cut properties also make it cost-effective to manufacture parts with complex shapes.
