AUGUST 27TH, 194a FLIGHT Advertisements. 13 ^ If may be alright for the aircraft industry, but 5? A PERTINENT QUERY, SIR . . . you are wondering what part aluminium alloys are going to play in shaping the post-war world. They will have much to do: their high strength-to-weight ratio, resist ance to corrosion, excellent heat conductivity and work ability will enable designers in many industries to cut deadweight, increase power/weight ratios and obtain improved performance. The tensile strength of many aluminium alloys is equal and even superior to that of steel. For example, Hiduminium R.R.77 has a tensile strength of 33-38 tons per square inch with a specific gravity of only 2.8. New developments in technique enable aluminium forgings to combine great structural strength with delicacy of design. Manu factured very close to final dimensions, great savings are made both in material and machining time. The aircraft industry, with its exacting standards, has been a proving ground for aluminium alloys, and the experience gained will be available for users in many industries. Full technical details are available on application both to present and prospective users of aluminium alloys. ffaluhUiiUitov & H I li H U U T * A i u u y s LIMITED SLOUGH
