What Are Aluminum 7075 Bars?

Aluminum 7075 bars are high-strength alloy bars primarily composed of aluminum, with zinc as the primary alloying element. Known for its excellent strength-to-weight ratio, 7075 bars are commonly used in aerospace, automotive, and structural applications where strength and lightness are critical. These bars offer exceptional corrosion resistance and are heat-treatable for enhanced mechanical properties.

Aluminium 7075 Bars are high-strength alloys primarily composed of zinc with magnesium and copper additions for corrosion resistance, making them suitable for applications exposed to harsh environments, from marine to aerospace sectors. Their corrosion-resistance ensures long term use.

7075 Aluminium Bars

Aluminium 7075 Bars may present challenges due to their hardness, however, with proper tooling and techniques they can still be machined effectively into precise shapes and dimensions for intricate components that demand high strength. Their excellent machinability also makes them valuable components in manufacturing complex products with strong resilience requirements.

Aluminum 7075 Bars stand out as being weldable materials, although not quite as easily as some of their alloy counterparts like 6061, such as due to proper welding procedures, preheating and selecting suitable filler materials will lead to strong welds with few or no defects.

Aluminium 7075 Bars have long been utilized by industries requiring lightweight yet high strength materials, including aerospace, automotive, sporting goods and structural applications. Their combination of strength, corrosion resistance and weight makes them essential in producing aircraft components, bicycle frames and structural supports.

Aluminium 7075 Bars have various applications across industries. Aerospace requires lightweight yet strong structures, in automotive production they contribute performance parts such as chassis components that improve vehicle efficiency and durability, sporting goods employ them in building high performance bicycle frames to withstand demanding conditions while sports use aluminium 7075 bars in building high performance bicycle frames and equipment, providing reliability under extreme stress conditions.

Manufacturing Process Of Aluminium Bars 7075

Casting

Melting and Casting

Steel and alloying metals are loaded into an electric arc furnace. Once in the furnace, the metal is heated to a specific temperature above its melting point, usually in excess of 2800°F.

Forming Round Bar

Forming

Most cast steel is formed by hot rolling—the slab, bloom, or billet is heated and passed through large rollers, stretching out the steel into a longer, thinner form.

Heat Treatment

Heat treatment

Heat treatment strengthens rolled stainless steel by recrystallizing the deformed microstructure. Most stainless steel is heat treated by annealing.

Descaling

Descaling

A rolled piece of stainless steel acquires a layer of oxidized “mill scale,” which needs to be washed away to restore a shiny surface finish.

Cutting Round Bar

Cutting or Machining

Stainless steel is cut to a specified shape and size. The stainless steel can be sheared with circular knives, sawed with high-speed blades, or blanked with punches.
