Aluminium Flat Bar

Aluminium Flat Bar Description

Overview:

An Aluminium Flat Bar is a versatile, solid metal stock manufactured primarily through an extrusion process. Known for its high strength-to-weight ratio, excellent corrosion resistance, and ease of machining, it provides a lightweight alternative to steel for structural, decorative, electrical, and manufacturing uses.

Key Characteristics & Advantages:

- Lightweight & Strong: Approximately one-third the weight of steel, making it ideal for weight-sensitive assemblies.

- Corrosion Resistance: Forms a natural protective oxide layer that resists atmospheric corrosion, rust, and chemical exposure.

- Workability: Highly machinable, easy to drill, cut, weld, bend, and anodize or powder-coat for custom decorative finishes.

- Electrical & Thermal Conductivity: Offers high thermal and electrical conductivity, making specific alloys suitable for electrical busbars and heat sinks.

Common Alloys & Tempers:

1. 6061-T6 (Structural Grade): 

   - High strength, good weldability, and excellent mechanical properties.

   - Used for structural frames, brackets, machinery parts, and truck beds.

2. 6063-T52 (Architectural Grade): 

   - Superior surface finish, smoother edges, and high corrosion resistance.

   - Ideal for trim, store fixtures, railings, decorative framing, and door frames.

3. 2024 / 7075 (Aircraft Grade): 

   - Ultra-high strength alloys used in high-stress aerospace and military applications.

4. 1100 / 1350 (Electrical Grade): 

   - High purity aluminium offering maximum electrical conductivity for electrical busbars and grounding bars.

Manufacturing Standards & Finishes:

- Standards: ASTM B221, EN 755, AMS specs.

- Finishes: Mill finish (standard raw extruded finish), Anodized (clear, black, or color-coated for corrosion protection), or Polished.

Primary Applications:

- Fabrication & Construction: Frame structures, bracing, base plates, and supports.

- Architectural Trim: Edging, molding, handrail components, and window/door frames.

- Transportation: Vehicle chassis components, trailer framing, and marine fixtures.

- Electrical Systems: Electrical busbars, transformer enclosures, and grounding strips.
