C12200 is Commercially Pure Copper,C12200 Copper Also known as deoxidized copper Phosphorus-Deoxidized Copper Tubes – C12200 – are extensively used in sugar refineries for condensers and evaporators. Deoxidized copper is the standard material for transferring heat from steam to water or air because of their excellent resistance to corrosion by fresh water and their high thermal conductivities.

C23000-(Red Brass)

Normally used for pipe and pipe nipples. Excellent cold working properties: common fabrication processes include forming and bending, threading and knurling. Red Brass is the best quality pipe for general plumbing purposes It has high corrosion-resistance to water. Furnished in semi-annealed condition

C26000-(Cartridge Brass)

This alloy offers the best combination of strength and ductility of all copper-base alloys. Soft temper is widely used for severe cold working operations such as deep drawing and spinning, half hard for stamping and fight bending and forming, spring temper combines mild rigidity with good appearance

Typical uses include architectural. automotive, hardware, industrial and munitions. Excellent cold working properties.

C27200-(Yellow Brass)

Available in tube. Excellent cold working properties
C33000-(Low Leaded Brass) Available in tube. The addition of low amounts of lead allow for some degree of machinability, together with moderate cold working properties.
