Shree Industries operates specialized sub-zero electrolyte baths (-4°C to 0°C) to generate dense, wear-resistant hard anodic coatings (up to 100 microns). This provides exceptional hardness (HRC 60-70) and dielectric strength (2000V) for machinery, pneumatic valves, and defense parts across Ahmedabad.
We support design engineering teams with detailed specs, alloy recommendations, and strict batch inspection standards.

Frequently Asked Questions
Why is my hard anodising coating flaking off cast aluminium parts?
Cast alloys containing high silicon (like LM6/LM25) can experience coating separation if electrolyte temperature or current density are uncalibrated. At Shree Industries, we use sub-zero electrolyte control (-4°C to 0°C) and custom electrical ramps specifically for cast grades to prevent peeling.
Which aluminium alloys are best suited for Type III coating?
6000 series (6061, 6082) and 5000 series (5052) yield excellent hardness. 7075 also produces highly durable coatings, while copper-heavy 2000 series requires special electrolyte parameters.
