C932 Bronze Test Panels
Metaspec makes test panels, specimens, coupons and catalysts from C932 bronze (also known as CDA 932, UNS C93200, or SAE 660). C932 is a high-lead tin bronze known for its antifriction and machining properties. These test specimens are cut from sheet or machined from plate or bar material. Customized 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.
