Silicon Brass Alloy

C87850 (Alloy C8785) is used in many typical applications:

  • Marine
  • Industrial Fields
  • Plumbing
  • Water Industry


C87850 (alloy C8785), like all alloys in the EZ-MELT Granular Ingots product line, meet ASTM standard B30. It is a highly fluid bronze alloy, pouring better than many leaded and bismuth brass alloys. It is often used in marine and industrial fields but is most commonly associated with PEX fittings and other plumbing products. It is also NSF 61 compliant, making it perfect for many applications in the water industry.

The granular nature of alloy C87850 (C8785) allows for increased surface area, reducing melting times in comparison to traditional brass and bronze ingot. This can help reduce melting times, saving you time, resources, and increasing profitability.
