Anti-oxidation Aluminum Tube

The Zenko factory's Anti-oxidation Aluminum Tube represents a critical advancement in aluminum tubing for electrical and industrial applications. Unlike standard aluminum tubes that suffer from surface oxidation and degradation over time, this product by Zenko incorporates a multi-layer anti-oxidation treatment that creates a durable protective barrier, ensuring consistent performance throughout the product's service life.

The core material is premium-grade aluminum alloy, selected for its optimal balance of electrical conductivity, thermal performance, and mechanical strength. The Anti-oxidation Aluminum Tube is manufactured through precision drawing processes that guarantee uniform wall thickness, smooth inner surfaces, and tight dimensional tolerances — ensuring reliable fit and easy installation across diverse equipment types.

What truly sets this product apart is the anti-oxidation surface treatment. Applied through advanced chemical conversion and sealing processes, this protective layer resists moisture, salt spray, atmospheric corrosion, and chemical exposure. The result is an aluminum tube that maintains surface integrity and electrical performance far longer than untreated alternatives, significantly reducing maintenance costs and system downtime.

Anti-oxidation Surface Treatment

The technology behind every Anti-oxidation Aluminum Tube:

Chemical conversion coating:  A chromate-free conversion layer chemically bonds to the aluminum surface, creating a dense, uniform protective film

Sealing process:  Thermal sealing closes micro-pores in the conversion layer, creating a continuous barrier against moisture and contaminants

Passivation enhancement:  Additional passivation treatment stabilizes the aluminum oxide layer, preventing further oxidation under operating conditions

Corrosion testing validation:  Every batch undergoes salt spray testing per ASTM B117 to verify ≥500-hour corrosion resistance performance

Surface conductivity preservation:  The treatment maintains electrical contact resistance below industry thresholds while providing full corrosion protection
