C87500 copper silicon brass bronze test panel specimen

875 Silicon Brass Test Panels

Metaspec makes test panels, specimens, coupons and catalysts from C87500 copper silicon brass (also known as  CDA 875 or silicon bronze). This is a copper/zinc alloy often used in casting applications. These test panels are available in a variety of sizes, including 1/2" x 3", 1" x 2", 2" x 4", and more. Custom test panels are available on request.

  • Test panels can be machined from plate or bar material. A wide range of sizes and thickness are available, including panels as thin as 0.032 inch. This process leaves some visible machining marks on the surface instead of an ‘as rolled’ surface finish.

    An additional polishing process can smooth out the machining marks on the faces of the test panel and is available upon request. Machined test panels are interleaved or packed individually to prevent surface scratches.
