CNC Machining
Aluminium 7075-T6 is a high-strength, lightweight alloy with a natural silver-white appearance. Its strength relative to weight makes it useful for demanding mechanical components, tooling fixtures and performance parts.
The T6 temper means the material has been solution heat-treated and artificially aged to increase strength and hardness. It is commonly selected for CNC-machined components where strength is a priority and the operating environment is carefully considered.
Custom parts are produced using CNC milling or turning, leaving fine tooling marks on as-machined surfaces. Protective finishes can be specified where available. Aluminium 7075 can be anodised, although colour and appearance may differ from other aluminium alloys.
Material
Aluminium 7075-T6
Description
Strengths
High strength relative to weight, good hardness and suitability for precision machining.
Weaknesses
Poor conventional fusion weldability, limited formability and susceptibility to stress-corrosion cracking in the T6 condition. Elevated temperatures can reduce strength.

Values shown are typical supplier figures for Aluminium 7075 and may vary with stock condition. Please confirm critical properties before production.
No. 7075 machines very well and produces a good surface finish. Its high hardness compared with 6000-series alloys helps with crisp edges and fine detail.
7075 is well suited to precision parts where stiffness and strength matter. Achievable tolerances depend on part size, geometry and features, so mark any critical tolerances on a 2D drawing with your upload and they will be reviewed and confirmed in your quote.
7075 can generally be anodised, although the colour can differ slightly from 6061 and anodising suitability is not specified for this stock. Please state any anodising requirement when you upload so it can be confirmed in your quote.
7075 is used for aircraft and aerospace parts, motorsport components, high-load jigs and fixtures, and defence and transport components where a high strength-to-weight ratio is essential.
7075 is roughly twice as strong as 6061 and is chosen for highly loaded parts. 6061 offers better corrosion resistance and weldability. 7075 is not suitable for conventional fusion welding and can be susceptible to stress-corrosion cracking.
The typical lead time shown for aluminium 7075 is 10 business days from an approved order. Quantity, finishing and any heat treatment can affect this, and your quote confirms the date before you order.
