EPi's E-Brite Ultra Cu process plates on all metals and works extremely well on zinc die-casts because it can withstand a large level of zinc contamination 2-3 grams/liter. Below is a part plated in the E-Brite Ultra Cu process.

Do you want to plate copper heat-treat stop off? E-Brite 30/30 process is Boeing approved. Our heat-treat stop off customers are informing us that they can plate less copper plating thickness with E-Brite 30/30 than with cyanide copper because it is a finer grain denser copper plate.
