How Master Alloys Are Made

If manufacturing products such as aluminum packaging is like making soup, then master alloys are like the seasoning that can make or break the end product. Master alloys combine a base material such as aluminum with other elements, depending on the desired chemistry of the finished product. Silicon and magnesium, for example, are two common agents in aluminum-based master alloys. 

The advantages of using Shapiro MasterAlloys include increased sustainability, more consistent melt rates, better recovery, and more efficient operations, among others. Shapiro MasterAlloys melt more consistently because the base metal and the alloying agent have already been brought into solution, which in turn enhances recovery. 

But since the metals are already in solution in a solid sow, you may be wondering how you can be sure that the chemistry remains consistent from lot to lot. At Shapiro MasterAlloys, we’ve engineered our production process to provide reliable, documented chemistry so you can rest assured that when you use our materials, you’ll receive in-spec, sustainable materials every time. Here’s how it works.

Sourcing Recycled Content for Master Alloys

Starting with high-quality recycled metals is key to achieving the right chemistry in master alloys. At Shapiro, we have a network of ten strategically located facilities across North America that source the specific aluminum types we look for. 

If you’re working with another master alloys supplier, it’s always best to select one that has a steady, reliable supply of base material so your production won’t be interrupted by shortages.

Master Alloy Production & Quality Testing

Shapiro Master Alloys proprietary blending process is carefully overseen by melt and metallurgy experts who make slight adjustments based on the chemistry of the inputs to yield an in-spec final product. Our materials also undergo extensive testing which results in an alloy report that certifies the contents of each sow. This certified report is sent to your team at Shapiro MasterAlloys to keep on file, which provides traceability and peace of mind that each sow is within your specific parameters.

Finished sows also undergo a safety inspection to ensure that they are free from inclusions (cracks). It’s important to prevent this moisture buildup because it could cause safety issues when melting the material.

Documentation and Traceability

When shipping master alloys to you, we send the corresponding chemistry analysis with every load. While we typically send a physical copy, we can also provide this information electronically. Certifying that your master alloys were produced from recycled content can help you demonstrate sustainable manufacturing practices to stakeholders, including on any ESG reporting you may provide.

Let Us Show You Consistency and Sustainability

Not only can Shapiro MasterAlloys help improve the results of your aluminum manufacturing process, but they are also better for the environment than primary materials. We can help you use more recycled content in your operation—so when you work with us, you join our team and other innovative manufacturers who are working to make the planet better together.
