Since 1988, Premier Aluminum LLC has been a trusted name in the U.S. aluminum casting industry, headquartered in Racine, Wisconsin. As a full-service, permanent mold aluminum foundry, Premier Aluminum offers end-to-end manufacturing solutions that combine precision, quality, and efficiency. One of the key capabilities supporting this excellence is Heat Treating — a critical process that enhances the mechanical properties, strength, and durability of aluminum castings. By performing heat treatment in-house, Premier Aluminum ensures every component achieves the right balance of hardness, ductility, and performance consistency. This integrated approach minimizes handling, reduces lead times, and guarantees the highest levels of quality control.

Heat Treating of Aluminum Castings
Advantages of Our Heat Treating
Premier Aluminum’s in-house heat treating delivers precise control over material properties and consistency across every part we produce. By keeping this capability under one roof, we eliminate third-party processing delays and maintain complete visibility from casting to finished product.
Key advantages include:
- Single-source solution integrating casting, machining, finishing, testing, and heat treating
- Consistent mechanical performance through controlled thermal processing
- Faster lead times and reduced supplier coordination
- Enhanced metallurgical integrity and dimensional stability
- Flexibility to support low- to medium-volume production
Our Heat Treating Process
Preparation & Setup
Each aluminum casting is carefully prepared for heat treating to ensure optimal thermal performance. Components are cleaned, inspected, and positioned to maintain uniform heating and cooling throughout the process. Material certification data is verified to ensure precise control of temperature cycles.
Thermal Processing
Premier Aluminum utilizes advanced ovens and programmable temperature control systems to execute precise heat treatment cycles. This includes solution heat treatment, quenching, and artificial aging to achieve desired mechanical properties such as tensile strength, elongation, and hardness. Every cycle is monitored and recorded for traceability and consistency.
Testing & Verification
Following heat treatment, each batch undergoes mechanical and dimensional verification to confirm conformance to customer specifications. Our in-house inspection team uses hardness testing and coordinate measurement machines (CMMs) to ensure parts meet required tolerances and performance standards.
Packaging & Delivery
After verification, components are packaged and prepared for next-stage machining, finishing, or final shipment. Customers receive parts that are fully heat-treated, traceable, and ready for integration into production.
