Low brass, UNS C24000, H08 Temper wire
Categories: Metal; Nonferrous Metal; Copper Alloy; Brass

Material Notes: Fair to excellent corrosion resistance. Excellent cold workability; good hot formability.

The Romans called this alloy "orichalcum", which also contained trace amounts of lead, tin, and other metals and was used to strike coins. Orichalcum is also the name of a naturally occurring gold-copper alloy that is only found in the Andes Mountains of South America.

Applications: battery caps, bellows, musical instruments, clock dials, pump lines, flexible hose.

Test specimen: wire - 2mm diameter.

Key Words: 80/20 brass, pump lines, flexible hose, flat products, wire, Low brass, UNS C24000, CZ103, ISO CuZn20, CEN CW503L, gilding metal, 80/20 brass, orichalcum
