Copper Alloy Wire, Beryllium Copper Wire


    At Radcliff wire we offer a large selection of Copper alloy wire, including Beryllium Copper wire. In the Copper based alloys, we offer different grades of Copper wire, Phosphor Bronze wire, Nickel Silver wire, and Beryllium Copper wire, and Brass wire, including Jewelry Bronze wire, Red Brass wire, and Yellow Brass wire. All of the above perform slightly differently with different load tolerances, corrosion resistance, hardness, and resistance to corrosion following welding or stress relieving.

    Provided below are charts displaying the various properties and specifications of all the types of Copper based alloys we sell. These charts should be of assistance in helping you to decide whether to go with a Beryllium Copper wire, a Yellow Brass wire or any of the other Copper based alloys.

    The Radcliff Wire staff is available to discuss your wire specification and needs to help you choose a copper based wire, or any other alloy wire that is best suited for your application.
