Leaded Nickel Copper Alloys
Materion Corporation offers innovative copper alloy products best suited to solving our customers’ specific material applications’ challenges.
In general, Nickel Copper Alloys provide improved strength and corrosion resistance while retaining good formability. They have excellent resistance to corrosion, which includes marine corrosion and biofouling. Lead is added to our copper alloys to provide added improved machinability. This additional lead acts also as a lubricant and, in the free machining grades, assists in chip break up.
Our Free Machining alloys can be cut quickly, easily obtain a good finish, and do not wear tooling down as much. They are designed to improve machinability without harming performance, keeping overall costs low for volume specific processes such as cold heading/cold forming.
Free Machining Alloys
Our leaded nickel copper free machining alloys are available in two compositions, each with its own physical and mechanical properties, ensuring our customers receive the solutions they require.
As a partner in our customers’ growth and profitability, we enable technologies by offering targeted alloy solutions designed to your specific need. We offer these high performance leaded nickel copper alloys with different characteristics and forms:
