110V 1000A Hard Anodizing Rectifier Power Supply

» Product Description

The Anodizing Rectifier delivers precise high-voltage control (up to 120V+) for hard anodizing. It supports currents from hundreds to tens of thousands of amps. Unlike decorative processes at 20V–24V, its high-frequency switching slashes oxide layer formation time by 30% and energy use. Compact design ensures stable current, enabling uniform Al₂O₃ films for corrosion-resistant, ultra-hard surfaces. Post-treatments like hot-water sealing integrate smoothly, boosting durability and color uniformity in dyed parts. With ±1% voltage stability, it produces repeatable aerospace and architectural components while reducing physical footprint and downtime.

» Product Applications

Anodizing Rectifier drives the electrochemical formation of aluminum’s oxide layer (Al₂O₃), critical for industrial applications demanding corrosion resistance and structural integrity. By delivering stable current outputs, it enables uniform growth of protective coatings with adjustable thickness (5–25μm), essential for automotive trim exposed to road salts or marine-grade architectural window frames. The technology ensures surfaces achieve 500–900 HV hardness for scratch-resistant smartphone casings while maintaining dielectric properties for heat sink insulation in 5G equipment. Post-anodizing, the rectifier-compatible sealing process locks in organic dyes for fade-resistant facade panels and medical device markings. Its adaptive voltage control (12–120V DC) supports both Type II decorative finishes on consumer electronics and Type III hard coatings for aircraft landing gear components, achieving 60% faster cycle times versus traditional rectifiers through pulsed current optimization.

» Role of Anodizing

Corrosion Resistance

Forms a protective oxide barrier against saltwater, chemicals, and atmospheric exposure, critical for marine hardware, aircraft components, and automotive underbody parts.

Surface Hardening

Achieves 300–500 HV surface hardness (vs. ~100 HV for bare aluminum), ideal for hydraulic systems, machinery guides, and industrial tooling requiring wear resistance.

Aesthetic Customization

Enables dyeing (organic/inorganic pigments) and electrolytic coloring for architectural façades, consumer electronics casings, and luxury packaging.

Electrical Insulation

Provides dielectric strength (15–25 V/μm) for heat sinks, PCB enclosures, and power distribution components needing non-conductive surfaces.

Adhesion Promotion

Microporous structure enhances bonding for powder-coated window frames, adhesive-mounted automotive trims, and composite aerospace panels.

Abrasion Resistance

Extends service life of conveyor components, firearm parts, and offshore rig equipment exposed to sand, grit, or high friction.

Thermal Management

Improves heat dissipation in LED housings, server racks, and EV battery trays via oxide layer’s emissivity (ε ≈ 0.7–0.8).

» Types of Anodizing

Anodizing rectifiers supply regulated current and voltage to electrochemically generate aluminum oxide layers, with core models such as the Aluminum Anodizing Rectifier (hard coating) and DC/AC Coloring Rectifier (integrated dyeing), each engineered for distinct process parameters.
