Mechanical Properties of C94100 Lead Bronze

Overview of C94100 Lead Bronze

1、 Main components

The main components of C94100 lead bronze include tin (Sn) content of 3.50-5.0, zinc (Zn) content of 2.0-6.0, etc.

2、 Physical performance

Purity related

Lead containing copper is divided into No. 1 and No. 2 lead containing copper. The purity of lead containing copper in No.1 reaches 99.97%, with an oxygen content not exceeding 0.003% and a total impurity content not exceeding 0.03%; The purity of lead containing copper No.2 reaches 99.95%, with an oxygen content not exceeding 0.003% and a total impurity content not exceeding 0.05%. There are also metal copper with OFC (lead containing copper) purity of 99.995%, as well as LC-OFC (linear crystalline lead containing copper or crystalline lead containing copper) purity of over 99.995% and OCC (single crystal lead containing copper) purity of over 99.996% (divided into PC-OCC and UP-OCC, etc.).

conductivity

When C94100 lead bronze is in a soft state, its conductivity is ≥ 58.0m/Ω. mm ².

3、 Mechanical performance

Performance in cast state

In the as cast state, the tensile strength of C94100 lead bronze is 340-450MPa, the hardness is HBS90-143, and the wear resistance exceeds the international standard brass CuZn40Pb and standard 5-5-5 bronze.

Other performance

It has good corrosion resistance, friction reduction and good casting performance; Low sensitivity to overheating and gas, good welding performance, no ferromagnetism, and low shrinkage coefficient.

4、 Material advantages

Comparison with other copper alloys

Compared with copper alloys, C94100 lead bronze has good flowability (95CM), reduced wire shrinkage (1.29%), low specific gravity (4.9), simple melting, improved working conditions, reduced environmental pollution, less burning loss, high yield, suitable for various casting methods, good processability, easy cutting, polishing, and decorative surface treatment.

Its wear resistance in the as cast state exceeds the international standard brass CuZn40Pb and standard 5-5-5 bronze, saving copper by more than 58% and reducing product costs by more than 50%; The melting point and pouring temperature are low, half of bronze and brass, saving 50% energy and increasing the lifespan of die-casting molds by 30 times.

Advantages in special environments

It can reduce 2-5 decibels of noise when used in textile machinery, has non sparking characteristics, and can be safely used in dangerous situations such as oil fields, oil wells, oil tankers, coal mines, natural gas, and coal gas. Forming by die-casting and other methods can greatly save the cost of precision machining for cast iron parts.

5、 Application Fields

Electrical and electronic field

Generally used in electrical and electronic applications such as audio equipment, vacuum electronic devices, cables, etc.

engineering field

Copper bar is a high current conductive product, suitable for electrical engineering such as high and low voltage appliances, switch contacts, distribution equipment, bus ducts, etc. It is also widely used in metal smelting, electroplating, chemical caustic soda and other ultra high current electrolytic smelting projects. C94100 lead bronze can be used as a material for copper bars and other related applications in these areas.
