Environment burden of four substances used in the key-making processThe materials that we use in the production of our "key blanks" do not pose environmental problems: |
|
Free Cutting Brass
Lead (Pb) Content…1% - 2% |
Free Cutting Nickel Silver
Lead (Pb) Content…0.5% - 1.5% |
WNS7
Lead (Pb) Content…less than 0.01% |
BERIC Alloy for Diecast Usage
BIT, TUBU and a certain number of other products we manufacture use BERIC. |
Iron
We believe that iron presents a number of problems as a raw material for key manufacturing. These drawbacks include magnetism, susceptibility to corrosion, susceptibility to cutting, etc. At present, Goto Manufacturing does not use iron as a raw material in our keys. |
Aluminum
The type of aluminum alloy best suited for key manufacturing presents a number of problems in our view. These problems include susceptibility to corrosion, susceptibility to color changes, and inferior durability. At present, Goto Manufacturing does not use aluminum as a raw material in our keys. |
Nickel Plating
The appearance of key plating differs widely from lot to lot. |
Nickel-Free Plating
Plating conducted as an anti-allergy measure. |
Chrome Plating
Goto Manufacturing does not use chrome plating due to problems involving hardness and thickness. |
