Specialists in Air Melt Alloys
Capabilities:
Focusing entirely on air melt alloy processing, AMT provides cast product across a breadth of materials to meet your specific alloy requirements. Using melt units from Inductotherm and Thermtronics, industry standard pre-heat furnaces from Pacific Kiln, and certified ingots from top alloy suppliers to the investment castings industry, AMT can transform raw materials into the quality castings you need. In addition to quality raw materials and top end processing equipment, AMT also employs best practices for alloy melting including inert gas blanketing, vacuum assist pouring for our solid mold products, and vacuum chamber pouring for aluminum shell molds.
Ferrous and Non-Ferrous:
Sourcing from certified master melters, AMT is capable of pouring a wide range of ferrous and non-ferrous alloys. We have expertise in pouring Nickel based, Cobalt based, Stainless, Aluminum and Copper based alloys as well as Tool Steels, and Carbon / Alloy Steels. Materials are ordered under the relevant material specifications including AMS, ASTM, MIL-S, MIL-A, and a host of other specs as required. All alloys are sourced in the US and are DFARS compliant.
Testing and Qualification:
Each alloy we purchase is melted to exacting specifications to meet your casting requirements. Every alloy is tested and certified at the source and certificates of conformance come with each shipment of material. In addition, all alloys go through a master heat qualification process once on site at AMT and include further chemistry and mechanical testing by certified independent labs to verify the integrity of the material we pour. If further alloy testing is required as part of a customer’s quality system, those specifics are noted in our integrated ERP system and appear on all shop paperwork. All parts cast at AMT are cross referenced to the original master heat for accurate lot traceability.
