Brass alloys are alloys of copper in which the zinc alloy in the amount exceeding 2% is the main component. Brass is divided into casting brass and wrought one.. Casting brass alloys, in addition to copper and zinc contain additives such as Pb, Mn, Fe, Ni - to improve the strength properties and corrosion resistance. Due to its liquidity such brass is good for form filling so that it is suitable for sand casting, gravity die and pressure casting.
We offer you castings in the form of centric sleeves, flanges, shafts, rods, strips, covers, plaques and shaped castings according to the customer needs. The weight of castings ranges from 0.2 kg to 200 kg. Our company offers casting in the following grades:
