With Brass

Cups, Crucibles, Cans

Yellow brass is one of many brass alloy metals consisting mainly of copper and a lower percentage of zinc. Many parts can be stamped from brass as it performs well for cold forming. It is also easily hot worked and hot forged for parts such as propane tank valves. In the automobile industry, connectors, antennas, radiators and many other items are all made of yellow brass, and most of our keys are made of it. Its unique acoustic properties make it excellent for musical instruments.
