Alcoa technical expertise helps Okaya reduce scrap rate by more than 90%

When Okaya first started using aluminum from a Chinese supplier, they encountered cracking and warping during manufacturing, resulting in a 25% scrap rate and escalation in production costs. If the problem could not be resolved, they would be forced to switch back to steel, despite its drawbacks. Instead, Okaya turned to Alcoa, the world’s leading supplier of aluminum, and its Consumer Electronics team for help.
