Gayatri Tubes is a leading manufacturer, wholesaler, and exporter of Cu 9010 Fasteners. We also deal in all stainless steel. Cu 9010 Fasteners is a manufacturer with the composition of copper, magnesium, zinc, nickel, iron, and lead. This fitting is manufactured with density 8,1g/cm3, melting point 1443 degree Celsius, tensile strength Psi- 80000, MPA -551, elongation 30%, and yield strength Psi- 35000, MPA – 241. Cu 9010 Fasteners is available in dimension ASTM, ASME, and API, with the specification ASTM/ ASME SB 111. These fittings are also available in grade of Cupro Nickel Cu- Ni 90/10 (UNS No. C70600). This fitting is manufactured in the form of Hex, Flat, Round, Square; wire in black & bright finish with length 100mm to 3660mm long. The Fasteners are from hot forged and cold-forged and with the type of screws, studs, cap screw, hex head bolts, hex coupling nut and many more.
The Fasteners is applicable in many industries like steam exhausts, architecture, aerospace industry, industrial chimneys, petroleum refineries, cooling towers, silos, sculpture, structural work, fertilizer, chemical plants, etc. Also, these fittings are useful for many purposes like construction, medicine, petrochemicals, energy industry, chemical industry, motor industry, food and drink industry, valve & pumps, transport and traffic, electronics and many more. These are even useful in tubular heat exchangers, high-pressure systems, piping, condensers, seawater system designs, and ships.
Cu 9010 Fasteners are high erosion resistance and seawater corrosion. This fitting during the manufacture is combined with a mixture of nickel and copper besides ferrous and manganese contents like iron which help to fight with the seawater corrosion and of their high quality and durability.
Cu 9010 Fasteners is useful because of its properties like fatigue limitation, highly corrosion resistance. They are highly resistant to salt solutions, hydrogen fluoride organic acids, alkalis, non-oxidizing acids, and carbon dioxide. Also there no risk of stress corrosion cracking, pitting corrosion and good resistance from ammonia containing gases. They are highly corrosion resistance in any temperatures with the help of given alloy DIN 17 471 during the manufacture. Also, it is highly electric resistive in low temperatures, good mechanical properties during both elevated and low temperature and good wear resistance.
