Rolls-Royce Limited, D E R B Y. YOUR REFERENCE:- Rm{William Robotham - Chief Engineer}/JBD.{John B. Dixon - Fuel Systems}8/AP. Dear Sirs, - BERYLLIUM BRONZE - Thank you for your letter of May 27th. The physical and mechanical properties of beryllium bronze are stated in the leaflet which we are pleased to enclose. From this you will see that in the solutionised condition beryllium bronze is about a 35-ton material, with a Vickers' Diamond Pyramid Hardness of 120 to 125. After completion of the second stage of heat-treatment (tempering) it achieves a maximum stress of about 80 tons per square inch, and a Vickers' Diamond Pyramid Hardness of 380 to 420. We consider that beryllium-bronze would be eminently suitable for the purpose you have in mind, and if you would give us particulars of the size and form in which you will require it, our Sales Department will be very glad indeed to quote you. Meantime, we beg to remain, Yours faithfully, FOR JAMES BOOTH & COMPANY (1915) LIMITED, DEVELOPMENT MANAGER. ENCLOS. LEAFLET. | ||
