Raw Materials - Alloys

Hi-Temp Products believes that Quality demands the utilization of Superior materials. Only miles away from the only US based Kanthal Sandvik Plant and 25+ years of working history with Kanthal as not only our primary Supplier but as a Customer, we consciously choose to source much of the alloy materials that go into our products through industry trusted Suppliers like Kanthal. Heating elements made from Kanthal alloys means superior adhesion properties of the surface oxide which equates to higher confidence and greater performance differences at higher temperatures. Hi-Temp chooses to carry on hand an extensive diversity of alloy materials with a high minimum quantity replenishment reorder philosophy to reduce stock out events, ensure material availability and ultimately protect our Customers’ precious equipment uptime.
