43、arried out by an arbitrator chosen by mutual agreement between supplier and purchaser. The arbitrators decision shall be final. EN 13981-2:2004 (E) 8 Annex A (informative) Guidelines for application and use A.1 Selection of alloys A.1.1 General The choice of the suitable aluminium alloy is determine

44、d by a combination of the factors strength, durability, physical properties, weldability, formability and availability. A.1.2 EN AW-6082 and EN AW-6061 EN AW-6082 is one of the most widely used heat treatable alloy and often the principle structural alloy in many countries for welded and unwelded ap

45、plications. EN AW-6061 is also a widely used heat treatable alloy for welded and non-welded applications. Both alloys are normally used in the peak aged T6 or T651 temper. The choice of these alloys as a structural material is based on a favourable combination of the properties: high strength after

46、heat treatment, good corrosion resistance, good weldability by both the MIG and the TIG processes, good formability in the T4 or T451 temper and good machinability. Care should be taken to account for the loss of strength in the heat affected zone (HAZ) of welded joints. Filler metals for welding ar

47、e specified in EN 1011-4. A.1.3 EN AW-5083 Among the alloys specified in the present standard EN AW-5083 is the strongest non-heat treatable alloy according to EN 485-2 possessing good welded properties and very good corrosion resistance. It is ductile in the soft condition with good forming propert

48、ies but looses ductility with cold forming, and can become hard with low ductility. This alloy is used commonly in Hxx tempers. However the alloy may in some tempers be susceptible to intergranular corrosion, which under certain circumstances, can develop into stress corrosion cracking under sustained loading. The use of this alloy is not recommended where the material is to be subjected to further heavy cold working and/or where service temperatures are expecte
