Q. What types of metal are used in making metal balls?

Answer

The material include in metal ball are tool steel, Alloy steel, Stainless steel, Carbon steel, Copper or copper alloys, Titanium or Titanium alloys, Nickel or Nickel alloys, Cobalt or Cobalt alloys, and specialized ferrous and nonferrous. The first step in making metal balls is rolling a wire into a ball. A pellet with a volume roughly equal to the ball with the desired outer diameter is obtained by shearing the wire (OD). Producing metal balls involves several stages. Rough machining and soft grinding are used to get rid of the forging flash. In order to increase the hardness of certain steel balls, a quench and temper heat treatment is applied.
