Smiths MRO is a sub-divsion of a larger business - Smiths Advanced Metals.
Smiths MRO focuses on raw material support for the global aircraft maintenance, repair and overhaul market. Our business is supported by a broad and diverse stock range with a dedicated team that provides outstanding service levels required for our industry.
7175 aluminium is a 7000 series alloy used for applications where high toughness and formability are necessary.
7175 aluminium plate combines many attractive performance characteristics. High mechanical strength, toughness and improved formability are features, along with improved stress corrosion resistance and high fracture toughness. Material hardening is achieved by heat treatment or cold working. The product is often referred to as a forging alloy and is often formed via die or hand forging. Stress corrosion cracking (SCC) is eliminated when the plates are supplied in the T7351 temper; this makes the product ideal for aerospace and MRO applications.
7175 aluminium plate finds use in structural aircraft applications, aircraft fasteners, landing gear and wing tension members. The alloy represents a stronger and tougher version of 7075.
We support the global MRO sector with 7175 material plate stock available to our customers with fast delivery times. We also process your aluminium plates in-house using dedicated plate saws where your product is cut to tight tolerances. We get you further ahead in the engineering process, which ensures that your aircraft returns to service quickly and safely.
The primary specification for 7175 aluminium plate is ASNA3050 which is produced from 6mm thickness up to 100mm thickness. The temper is T7351, which offers high resistance to stress corrosion cracking. The T6 temper is unsuitable for aerospace applications due to its susceptibility to stress corrosion cracking (SCC).
Wing tension members
Very high tensile strength
Not susceptible to stress corrosion cracking
