三鷹金属化工所 List of Products and Services

We would like to introduce our 'hard chrome plating (industrial chrome, Hcr, HCR)' that can be processed at our headquarters factory. It features a thicker plating than decorative chrome and is widely used for industrial machine parts due to its excellent wear resistance. Processing can be done at lower temperatures compared to heat treatment. Knowledge such as the arrangement of anodes, shielding plates, and etching treatment according to the material and plating thickness is required. 【Features】 ■ High hardness ranging from Hv800 to 1000 ■ Excellent wear resistance ■ Excellent corrosion resistance ■ Low friction coefficient ■ Good release properties *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce our 'Zinc Plating (Zn, ZN, Unichrome/Yellow)' that can be processed at our main factory. The tank size is 1200×1300×800 mm. This processing has excellent rust prevention properties for iron. Additionally, since zinc is a more electrochemically active metal than iron, it acts as an anode in corrosive environments and corrodes sacrificially, thereby protecting the iron. 【Features】 ■ Excellent rust prevention for iron ■ Zinc is a more electrochemically active metal than iron ■ Tank size: 1200×1300×800 mm ■ Subject to steel materials, with exceptions *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce "Aluminum Chromate," which can be processed at our headquarters factory. The yellow-coated film "Alozin 1200" is primarily used to enhance corrosion resistance and as a pretreatment for painting. By changing the processing time, it is possible to adjust the contact electrical resistance value. The colorless-coated film "Alozin 1000" is used for enhancing corrosion resistance and as a pretreatment for painting, just like "Alozin 1200." Additionally, because it is colorless, it is also suitable as a base for clear coating that highlights the aluminum material. 【Features of Alozin 1200】 ■ Yellow-coated film ■ Primarily used for enhancing corrosion resistance and as a pretreatment for painting ■ The final color may vary slightly depending on the type of material and processing method ■ It is possible to adjust the contact electrical resistance value by changing the processing time *For more details, please refer to the PDF document or feel free to contact us.
