Copper is an excellent electrical conductor allowing easy brazing
Brass is an alloy consisting of copper (Cu) and zinc (Zn). The most commonly used alloys contain 5 to 45 percent of zinc. Copper and zinc are joined optimally in the cast and remain cast evenly also during solidification. Approximately 60 different types of brass exist allowing virtually all physically, chemical and technological properties to be produced. Depending on the purpose, Krause Precision Chill Casting also processes special brass with as aluminum, lead, nickel or silicon added on.
Brass alloys are the best material for engineering parts of medium solidity. Additionally, the material scores if filigrane, thin-walled casting parts are requested: Krause Precision Chill Casting produces wall thicknesses from 2.5 millimeters depending on the geometry. And brass has another important advantage: the material is very much resistant to corrosion, a fact which Krause Precision Chill Casting often makes use of. Our specialty: the complex cast of lead-free copper alloys. Another specialty: a special copper zinc alloy resistant to corrosion by chemicals is even seawater resistant.
Brass alloys are used to produce controls and instruments and are basically interesting in different industries – from printing and packaging over to the car, textile machine or medicinal engineering industries.
