Heat Treatment of C93700 Lead Bronze

Overview of C93700 Lead Bronze

1、 Basic Information

C93700 is an American standard lead bronze material, also known as SAE64, belonging to high lead tin bronze material.

2、 Chemical composition

Copper surplus, tin 9.0-11.0, lead 8.0-11.0, zinc ≤ 2.0, nickel ≤ 2.0,

3、 Physical properties

The density is 8.7g/cm ³ and the melting point is 1030 ℃.

4、 Material characteristics

In terms of mechanical performance: it has high strength, high hardness, elasticity and wear resistance, and does not produce sparks when bumped.

In terms of processing performance, it is easy to weld and can be processed through stamping, compression molding, stretching, bending, and other processes. It can also be processed in a hot state, but the tendency for hot cracking is relatively high.

In terms of friction reduction and cutting performance: it has high friction reduction and good machinability, and is easy to weld and brazing.

In terms of corrosion resistance: It has good corrosion resistance in atmosphere, fresh water, and seawater, and is suitable for equipment working in high-speed, low load, and harsh environments, such as crushers.

5、 Application Fields

Widely used in fields such as ships, automobiles, machinery, electricity, and chemicals, it is used to produce various machine tool bearings, sliding bearings, mechanical seals, valves, gears, and other components. Widely used in the instrument manufacturing industry, mainly for manufacturing elastic components, wear-resistant parts, and metal mesh, etc; In the aviation industry, it is mainly used as a diaphragm, tension, etc. for combination airspeed indicators, intake pressure gauges, etc.
