The provider offers KMZ brass brand CW617N (CuZn40Pb2) at economical price. Regular customers can take advantage of the discount discount. The provider ensures timely delivery of products to any email address. The price is the best in this segment of the rental.

Technical characteristics

Alloy CW617N (CuZn40Pb2) is a wrought brass with an increased lead content. This alloy provides good machinability on machine tools, as well as lower friction in mechanical contact with moving parts. This grade of brass is used mainly for the primary plastic deformation in hot or Polygonatum condition, has a moderately low cost, has a relatively low melting point and a moderately high rate mechanical tensile strength.

Chemical composition EN 12164

Copper Aluminium Iron Nickel Lead Tin Zinc Impurities (magnesium, silicon, bismuth, arsenic)
57…59 ≤0,05 ≤0.3 mm ≤0.3 mm 1,6…2,5 ≤0.3 mm The rest ≤0,2

The alloy has good corrosion resistance and heat resistance but is not resistant to inorganic acids. Usually comes after rolling, without prior heat treatment. Typical parts made from alloy art decals under the engraving, valves, gears, fasteners, decorative metal.
