Arcast Arc 50

Arcast Arc 50 melter in action

Our smallest machine

This vacuum arc melter allows metallurgists and technicians to alloy reactive or nonreactive metals, and cast these alloys with the lowest running and capital costs, while maintaining a high engineering standard.

The Arcast Micro Vacuum Arc Melter offers the ability to melt, cast and rapidly solidify metal alloys of nominal 50 gram mass using a clean, ceramic-free cold crucible process. You can use it to melt and alloy metals at over 3400℃, such as titanium alloys, memory alloys, HEA (high entropy alloys), RHEA (refractory, high entropy alloys) and bulk amorphous glass alloys. The furnace is enclosed in a quartz vacuum chamber and offers many standard options.



Button casting

Water cooled button casting crucibles are machined from oxygen-free copper and allow the melting of small experimental samples for testing.

Titanium getter

If you need to absorb stray gasses in the chamber we can supply a titanium getter.

Custom crucibles

We can machine copper or graphite crucibles to your specification for your unique needs.

Two vacuum options

Medium (1E-2 mbar) and High (5E-6 mbar). Both options are designed for quick cycle times and user friendly operation.
