Metalwerks Vacuum Arc Remelt (VAR) furnaces have an extensive range of capabilities. The crucible sizes range from 2.5” diameter and up to 20” diameter. The furnace is setup to melt Fe, Ni, Co, Ti, and Zr alloys. This furnace is used to remelt VIM or ISM ingots into larger ingots for processing. The melting is controlled by a PLC, and the robust vacuum system creates very high purity material with low inclusion content.
Metalwerks utilizes two different VAR furnaces. Our research VAR casts electrodes that are either 2.5” or 4.5” diameter and up to 10” in length. Our production VAR is capable of melting ingots as small as 6” diameter, weighing around 150 pounds, and can go all the way up to 20” diameter at around 6000 pounds.
We have a large selection of crucible sizes in between this range. The table below lists the crucible sizes we currently use.
