Failure in compliance to chemical composition of alloyed aluminum may result in brittleness of the casting part. Thus, before reaching the furnace, it’s an essential first step to test the chemical composition of the raw material.

Victor has adopted the Germany-made Spectra Spark OEM to perform test of aluminum ingot for our casting line. The device is merited for its high-speed analysis (20 – 30 seconds), high-definition analyzing ability, complete data coverage on metal alloys (including data reading on aluminum up to to 0.000000%), and high anti-jamming to surroundings.

As soon as raw material (or ingot, to be specific) is received at Victor, our QC inspector will take out a piece to be tested in the spark chamber. In the chamber, argon gas is pumped 3-6 times in order to evacuate oxygen from the air in the chamber for optimum testing accuracy. The sample is tested in such vacuum condition to verify chemical compliance before the batch material is released to the furnace for the casting process. This enhances production stability of our casting products.
