Our long year of experience with aluminium and stainless steel has taught us many valuable lessons that are built into our products. It is not enough simply to specify a suitable grade of materials on a drawing, constant checks must be made on the material and the supplier must fully understand the end use. All materials we use are fully traceable so as to ensure that our customers get the best possible product, which, provided it is kept clean and serviced, should last longer than the vehicle on which it is installed.
Most of our parts are made from aluminium alloy either forgings or solid billets. The materials being 6082 or 6262. The listing of these materials tells only part of the story because the international specifications allow for significant variations in the composition of the material used for billets. Unfortunately these variations in chemical composition do not show themselves until the parts are anodised, that is when all the machining and pre-anodise operations are complete. We discussed our problems with many aluminium mills only to be told that they supplied material to international specifications. Our quality records told us there was one mill, who supplied material that never gave problems so we approached them. They listened carefully to the stories of our problems, convinced us that they fully understood the problem and promised that they had a solution. They have kept their promise so, in our opinion that makes them the best. The company is called Eural Knutti and they are based in Brescia , Italy .
The stainless steel we use for the levers fitted the Aero 200, 300, and 500 is the same material as is used by the medical profession for hip joint. Simply the best stainless steel that can be bought.
One of the most common plastic materials used for fuel systems was nylon but the change in gasoline formulations meant that this material is no longer suited to use with the latest fuels. We now use a special grade of acetal, jointly developed by Mercedes Benz and Celanese. This material resists all known fuels, even the latest types developed under the sustainable fuels programme.
