Dedacciai aluminum tubing constitute a large family of high performance products. Dedacciai designs and manufactures light aluminum alloy tubing more than 20 years ago, and this catalogue is the result of our passion and millions of kilometers rides all over the world roads by our testers, professional teams athletes, cyclists and friends. Dedacciai light alloy tubing are available in two classes: - AEGIS class tubing: state of the art light tubing, designed for racing and high performances frames. They are made of Scandium, and En-aW 7020 alloy - FIRE class tubing: designed and engineered for the maximum reliability and easy frame assembling. They are made of alloy. all our aluminum tubing are seamless, manufactured and heat treated with water quench technology in our plant in Campagnola Cremasca, italy. in order to obtain the best results from the use of this class of products, please look carefully at the drawings, and read our advices at the end of this catalogue. aluminum 2

Assembling of the tubing Geometrical features all the Dedacciai tubes and tube sets are designed for assembling frames based on current uci geometry. in the choice of tubing for manufacturing a frames, please keep into account the following safety rules: Verify that for the selected geometry you will save a butt length longer than the thermal affected zone, and in any case longer that the tube diameter. If the butt length of down and top tubing butts are not symmetrical, pay attention in the tube orientation : at the head tube joint the tube must be only mitred, and not cutted. Depending on geometry, it is always better to keep top and down tubing spaced on head tube. Over imposed tubing geometries are less safe. recommended tubing can t be used for offroad frames. Fixing point and welding cordons closure points can give origin to fatigue cracks, realize them in the less stressed areas of the joints. It is recommended to completely weld the seat tube on bottom bracket, and then all other tubing. Top tube and seat stays must be approximately aligned at the seat tube joint. if you want to weld the seat stays below the top tube center line, please use the low geometry (lg) seat tubing. Do not grind and/or polish the welding cordons. The risk of reducing the tube wall thickness is too high! aluminum 22
Welding and post-welding advices After cutting and before welding the tubing, brush the ends of them with care, using inox brush or 3m Scotch Brite, in order to remove oxides and deburr the milled edges. The edges must be smooth and without notches. after mechanical action, use alcohol to degrease and clean the welding surfaces. All the Dedacciai aluminum alloy tubing are compatible, and can be welded together. Suggested welding wires are: for and 7020 tubing -> 5356 or 5183 for Scandium tubing -> Dedacciai Sc wire MWR2401000SC Dedacciai Sc wire is supplied free of any charge with scandium tubing, or can be bought as spare part. Dedacciai recommend to use components in 7020 or alloy for structural reasons in the frame fabrication. if it is necessarily to use other alloys, suggested welding wires are: For 5000 alloy series components: S-al mg 4,5 mn (5183) For 00 alloy series components: S-al Si 5 (4043) or S-al mg 5 (5356) After welding, artificial aging of the frame is strongly recommended within 7 days from the manufacturing date. This heat treatment acts as hardening process for the thermal affected zones, and as stress relief treatment for the whole structure. it is very important to assure long term reliability of the frame. The suggested parameters are: 120 C +/- 5 C for 12 16 hours 7000 alloys are sensitive to corrosion and tensile-corrosion phenomenon. Anticorrosion treatment is needed on the finished frame, before painting stage 7000 alloys frame are sensitive to high temperatures, please make sure that during the painting stage frames do not exceed 165 C. 23
