Chromate conversion coating

What Is Chromate Conversion Coating?

Chromate conversion coating is a chemical process applied to aluminum and other metal surfaces to enhance corrosion resistance, improve paint adhesion, and maintain electrical conductivity. 

At MYT Machining, we offer both trivalent and hexavalent chromate coatings, compliant with industry standards, including MIL-DTL-5541 Type II chromate. This is a popular surface finish in the aerospace, defense, automotive, and electronics sectors, where conductivity and durability are key factors.

Benefits of Chromate Coating

Our chromate coating service is engineered to meet high-performance demands while being environmentally compliant. Key Advantages include:

• Excellent corrosion resistance
• Retention of electrical conductivity
• Able to be secondary processed
• Trivalent and hexavalent forms are both available

Applications of Conversion Coating

This coating is perfect for:

• Aerospace parts
• Defense components
• Electronic housings
• Accurate machined aluminum finish surfaces
• Industrial and automotive brackets

Whether you require trivalent conversion chromate coating for RoHS compliance or the Cronak chromate process for zinc, MYT Machining delivers consistent results with tight process control.

Hexavalent vs Trivalent Chromate Coating

Here at MYT Machining, we have both types based on your application needs:

Properties of Hexavalent Chromate:

• Traditional standard
• Better corrosion resistance
• A little more poisonous; prohibited in a few localities;

Properties of Trivalent Chromate:

• RoHS compliant
• Safest and eco-friendliest
• Electronic and aerospace applications
• Hassled to endure severe conditions.

We ensure our chromate coatings pass standardized corrosion tests, including:

• Salt spray tests
• Humidity resistance tests
• Tape tests and electrical tests

Our chromate conversion salt spray test data supports durability in extreme conditions.
