Stainless Steel SUS303, SUS304
303/304 is a free machining chromium-nickel austenitic stainless steel with good strength and good corrosion resistance.Material non magnetic in the annealed condition, but can become mildly magnetic following cold working. Annealing is required to rectify if necessary.
Description:
Used extensively by the Food Processing, Dairy Equipment, Dying Industry, Architectural Equipment, Hardware and Kitchenware Manufacturing Industry, Chemical, Petrochemical and Transport Industry etc..

Aluminium Alloy
Series 1xxx: 1050, 1060, 1070, 1080, 1100, 1435 other(are essentially pure aluminium with a minimum 99% aluminium content by weight)
Series 2xxx: 2011, 2014, 2017, 2024 other (are alloyed with copper, can be precipitation hardened to strengths comparable to steel. Formerly referred to as duralumin, they were once the most common aerospace alloys, but were susceptible to stress corrosion cracking and are increasingly replaced by 7000 series in new designs.)
Series 3xxx: 3002, 3003, 3003, 3104, 3204, 3030 other(are alloyed with manganese)
Series 5xxx: 5005, 5025, 5040, 5056, 5083 other(Very good resistance to corrosion and oxidation. For parts with a good mechanical strenght and improved fatigue resistance.)
Series 6xxx: 6101, 6003, 6061, 6063, 6020, 6201, 6262, 6082 other(For machinery components, structural elements. It offers resistance levels higher than the 5xxx series alloys and has a good resistance to corrosion.)
Series 7xxx: 7003, 7005, 7050, 7075 other(Aeronautical alloy: gears and shafts, bicycle and motorbike frames, sprockets, aerospace implementation, nautical engines, moulds, others)
