Anode for Heat Treating Aluminum in Spherical Shape
High-quality aluminum condenser anodes for superior corrosion protection in diverse environments.
Description
This spherical aluminum anode serves as a convenient sacrificial anode that can be easily replaced. It is designed for use in heat treaters, pressure vessels, and various production vessels. These anodes are specifically effective in environments with high temperatures and low chloride content in either saltwater or freshwater conditions.
Quality Substrate Material
Crafted from an alloy with high voltage and high potential, our aluminum spherical anode is engineered to comply with ISO, NACE, and DNV standards.
