Nickel-free platings

One reason for metal allergies is as follows:
When metal ions from sweat or other sources combine with proteins in the body, they can transform into allergens that can trigger allergic reactions to some individuals. Thus, it is unsuitable to use plating that is prone to causing allergies in products that frequently come into direct contact with the skin.

As a countermeasure, consider using materials or plating metals that are less likely to trigger allergic reactions.

At Mitsuya, we can provide the following plating (metallization) technology with low allergen risk:
・Direct Gold Plating on Stainless Steel (SUS)
・Direct Silver Plating on Stainless Steel (SUS)
・Direct Tin Plating on Stainless Steel (SUS)
・Gold Iron Alloy Plating
・Copper Tin Alloy Plating
・Copper Tin Zinc alloy plating

Available platings

Copper Tin alloy plating (metallization)
Copper Tin Zinc alloy plating (metallization)
Direct Gold plating on SUS without Ni under plating
Direct Silver plating on SUS without Ni under plating
Direct Tin plating on SUS without Ni under plating
Gold Iron alloy plating (Cobalt and Nickel free)
