Brass is an alloy made from a mixture of copper and zinc. Brass is available in many different forms, each with different properties depending on the ratio of copper and zinc in the alloy.

Brass and bronze are similar metals. Historically, brass has been popular for its gold-like appearance. It is commonly used in applications that require corrosion resistance and low friction. It is also used in applications where sparks cannot be struck, such as in fittings and gaskets used near explosive and flammable materials.


All types of brass have these characteristics:

  • Strong
  • Machinable
  • Low melting point
  • Durable
  • Non-magnetic
  • Conductive (electric and thermal)
  • Corrosion-resistant


Free Cutting Brass (alloy C360)

Alloy C360 brass, also called free cutting brass, contains copper, zinc, and lead. Alloy C360 brass offers the same durability and corrosion resistance found in other forms of brass.

Gilding Metal (Red Brass)

Gilding metal, or red brass, is an alloy consisting of 95 percent copper and 5 percent zinc.

Engraving Brass (alloy C35600 or C37000)

Engraving brass, also referred to as alloy C35600 or C37000, contains from 1 percent to 2 percent lead.

Arsenical Brass (alloy C26000, C26130 or 70/30)

Arsenical brass (C26000, C26130 or 70/30 brass) contains approximately .03 percent arsenic, which improves corrosion resistance in water. Like other forms of brass, arsenical brass is bright yellow, strong, and easy to machine.

High Tensile Brass

High tensile brass is a robust alloy that includes a small percentage of manganese. Its strength and non-corrosive qualities make it ideal for applications subjected to high stresses.
