Aluminum Alloys

All alloys used in our foundry’s castings are guaranteed to meet specification. Each pour is analyzed on our Spectrograph to ensure proper chemistry. This “in-house alloying” capability ensures actual chemistries are always poured regardless of unforeseen variations in holding time. Additionally, this ability allows us to work closely with our customers in developing new alloys.

Certification Options

Erie Bronze offers various levels of quality assurance for alloy chemistry.

Nominal Composition: means testing the heat of material and adding the necessary additives to bring the material into specification.

Actual Chemistry: means testing the heat of material, adding the necessary additives to bring the material into specification and taking a final chemistry coupon at the time of pouring.

Actual Chemistry with Test Bars: means testing the heat of material, adding the necessary additives to bring the material into specification, taking a final chemistry coupon at the time of pouring, and pouring test bars for physical property analysis.
