22 Advertisements. FLIGHT APRIL IITH, 1946 ALUMINI UNION LIMITED A fully-owned subsidiary of Aluminium Limited, Montreal. Canada. GROSVENOR HOUSE, PARK LANE, LONDON, W.I for modern transport Aluminium is in the air—aviation depends on it. Ships, motor care, omnibuses, locomotives and railway coaches, are using more and more of this versatile metal — so strong, yet light, rustproof and decorative. In vast expansion of world transport aluminium will play a major part because it is the engineer's metal, and it is available in inexhaustible quan- tities. Before the war the price of aluminium had always shown a ten- dency to drop; now the war is over this tendency has been resumed and the cost of aluminium today is already below the pre-war level. Have you ex- plored the potentialities of aluminium and its alloys? Ask us about uses and supplies. • YOU'RE TELLING US! The frequent enquiries we are getting from all manner of industries tell us what a great post-war future awaits ON AZOTE II in all fields where thermal insulation and lightweight construction are of prime importance. ONAZOTE II, made entirely from high-grade synthetic rubber, is now fulfilling the demands originally satisfied by ONAZOTE I, a natural rubber product which is no longer available. WHAT IS ONAZOTE II ? ONAZOTE II Is an expanded hard synthetic rubber material withexceptional thermal insulating properties. It possesses mechanical and physical properties equivalent in every way to natural rubberand yet has the added advantage of a higher soften-point, thereby rendering it more suitable for use under tropical conditions. It isextremely light and buoyant, yet strong enough to meet all demands. It is non-warping and non-water-absorbent; bacteria and verminproof; not subject to deterioration. HOW rS ONAZOTE II USED ? ONAZOTE II is ideal for use as a low density stabilising core in theconstruction of deck-housings, partition walls, panelling, doors, furni- ture and interior fittings. Adhered in the well-known "sandwich "technique between wallboard, plywood veneers, aluminium, lightweight alloy sheets or other suitable material, it finds a place in flat or curvedpanel work. It can also be supplied in various moulded sections. As a buoyancy material it is particularly suitable for the constructionof floats, mooring buoys, pick-up buoys and various types of life-saving appliances. WHAT GIVES ONAZOTE II ITS LOW THERMAL CONDUCTIVITY ? The unique non-intercommunicating cellular construction of ONA- ZOTE II and its allied materials eliminates convection currents and thus provides an insulating medium of the highest known efficiency. •jlr There is probably a use for ONAZOTE II in your business.
