Anti-Corrosion 3003 H14 Aluminum Round Bar Weather Resistant Chemical Equipment Rod

Anti-Corrosion 3003 H14 aluminum round bar is a manganese alloyed aluminum product developed for applications that demand dependable resistance to weathering, moisture, and mild chemical exposure. The 3003 grade offers roughly 20% higher strength than pure aluminum while retaining excellent workability, which makes it a practical choice for chemical processing equipment, storage tank components, and outdoor structural supports. Its naturally forming oxide layer provides steady protection in humid, coastal, and industrial atmospheres.

The bars are extruded or drawn to the H14 temper to deliver a smooth surface and stable dimensions, allowing reliable bending, machining, and welding. Because 3003 resists attack from many mild acids and alkalis, it is frequently selected for piping supports, ventilation components, and heat transfer parts where painted steel would corrode. When a project requires a balance of corrosion resistance, formability, and cost efficiency, anti-corrosion 3003 aluminum round bar is a dependable engineering material.

• Superior Weather Resistance: Manganese alloying delivers steady protection against rain, humidity, and atmospheric corrosion.
• Mild Chemical Resistance: Performs well against many mild acids and alkalis in chemical processing service.
• Higher Strength Than Pure Aluminum: Approximately 20% stronger than 1050 while remaining easy to form and machine.
• Excellent Formability: H14 temper supports bending, flanging, and deep drawing without cracking.
• Good Weldability: Suitable for MIG and TIG welding with reliable joint integrity after welding.
• Stable Dimensional Tolerance: Controlled extrusion keeps diameter and straightness consistent along each bar.

Anti-corrosion 3003 round aluminum bar is used for chemical storage tank fittings, process piping supports, ventilation ducts, heat exchanger components, outdoor signage frames, roofing accessories, and industrial equipment housings. It also suits general fabrication and marine hardware where moderate strength and stable corrosion performance are preferred.

The alloy is melted with controlled manganese additions, cast into billets, and extruded to form round profiles. Subsequent cold drawing to H14 raises the mechanical strength and improves surface quality, while the manganese dispersoid phase strengthens the matrix and helps the surface resist localized corrosion attack.

The bars are protected with film wrapping and shipped in export seaworthy wooden pallets or steel strapped bundles. A mill test certificate is supplied with every batch, and we provide tailored packing, marking, and third party inspection to meet your procurement requirements.
