The AIVAF metal melting furnace stands as a compact arc melting furnace, adept at transforming alloy ingots through multiple smelting cycles while preserving the controlled atmosphere intact. It facilitates the preparation of numerous samples concurrently, making it an optimal apparatus for universities and research institutes engaged in the creation of refractory metal and metal carbide samples.
An arc melting furnace melts metal with an electric arc from a tungsten electrode while the sample sits on a water-cooled copper hearth, so the melt never touches a ceramic crucible that could contaminate it. Melting under high vacuum or a clean argon atmosphere keeps reactive and refractory metals from oxidizing.
- Five hearth positions: three alloy melting positions with magnetic stirring, one ingot casting and one degassing position
- Up to 157g per position (calibrated with iron)
- Manipulator flips ingots under vacuum, so they can be remelted several times for an even alloy
- Suction casting chamber with a 6mm mold interface
- Molecular pump system reaches an ultimate vacuum of 6.67 x 10^-4 Pa
It needs a 480V three-phase supply, cooling water and high-purity argon or 5% H2 in argon during melting.

What customers say about our store
Quick and reliable service provided! - Scheduled an appointment with Wayne the other day for a Dry Ice order pick up, he will go over and above for his customers to make sure we are well taken care of. Even with a broken foot !
Thanks again Wayne!
You've got my business!
Wayne there has an excellent store, he has everything, really nice stuff at good prices, ultimately very fair compared to others. I will certainly be going back for everything I need. Got some things from a different place and spent 50% more, just go see Wayne first, he seems like he wants to help you out more than sell you out the door.
WOW
I'd like to first start with this business witch is great ,location was easy to find with good directions, the services wayne offers are a excellent industry best, I had items shipped and also picked up at business store front both very easy and quick
Also like to add the quality of the equipment sold as anything with logo extractor king is from my experience also again an industry best!
And last owner and…
