DTD 627

CZ131 or commonly known as DTD 627 in the Asian Sub-continent, is a riveting and turning brass quality grade with improved ductility. This alloy offers a good corrosion resistance along with high strength characteristics which results in excellent formation for bending and cold heading. CZ131 contains higher amount of Copper percentage which makes it an ideal choice for components that require crimping and machining on the head parts.
