Top 5 Copper Alloys for Exceptional Machining Performance

Copper alloys are widely used in various industries due to their excellent mechanical properties, corrosion resistance, and ease of machining. In this blog post, we will explore the top five copper alloys that offer exceptional machining performance, making them the ideal choice for a wide range of applications.

1. Brass (C36000)

Brass, specifically C36000 or free-cutting brass, is one of the most popular copper alloys for machining. It contains around 61% copper, 35% zinc, and 3% lead, which gives it excellent machinability, corrosion resistance, and good strength. This alloy is widely used for making gears, valves, nuts, and bolts.

2. Bronze (C93200)

C93200, also known as bearing bronze or SAE 660, is a popular copper alloy for machining due to its excellent wear resistance, strength, and anti-friction properties. It contains approximately 83% copper, 7% tin, and 7% lead, making it ideal for applications such as bearings, bushings, and thrust washers.

3. Copper-Nickel (C70600)

Copper-nickel alloys, specifically C70600 or 90/10 copper-nickel, provide excellent corrosion resistance, especially in marine environments. This alloy contains around 90% copper and 10% nickel, offering good machinability and strength. It is commonly used for marine hardware, heat exchangers, and piping systems.

4. Aluminum Bronze (C95400)

C95400, also known as aluminum bronze, is a high-strength copper alloy with excellent wear resistance and anti-corrosion properties. It contains about 85% copper, 11% aluminum, and 4% iron, which gives it excellent machinability and strength. This alloy is widely used for making gears, valves, and wear-resistant components.

5. Tellurium Copper (C14500)

Tellurium copper, or C14500, is a copper alloy with enhanced machinability due to the addition of tellurium. It contains

CNC Copper Machining

CNC Machining Copper Material is good electrical conductivity, thermal conductivity, it is soft and good for machining as it has high plasticity, it is easily and rapidly to carry out desired shape as machining cutter can run faster than other steel materials, and also reach high precision.

Copper has a shiny reddish-orange finish, which varies slightly based on the surface finish method. Copper can be media-blasted and polished to achieve many different cosmetic surface finishes.

CNC Machining Copper Parts are widely used in the manufacture of electrical wires, cables, electric brushes, electric spark, and other electrical devices and products.

Benefits of CNC Copper Machining

1/ CNC Machining Copper Parts are excellent in electricity conductivity, supporting very good electric function

2/ CNC Machining Copper Parts are soft, easy to design into different shape, also suitable for many processes

3/ Copper is easy for cutting and machining, its production efficiency is much higher than steel series

4/ Good propriety for bending and shaping

5/ Heat transferring function very good, high resistance, temperature stability, long durable using

6/ Stable surface, non-surface treatment is durable, electroplating is also used on copper parts
