Sachiya Steel International is one of the Leading Manufacturer And Exporter Of High Quality Aluminium Bolts And Nuts, which is available in different designs, shapes and sizes for our customers at best rates. For maximum corrosion resistance to chemical environments, it is essential that the surface of Aluminium 6061 Hex Head Bolts be free of all heat tint or oxide formed during annealing or hot working. Aluminium 6082 Hex Head Nuts is cold worked using standard tooling, where no obvious difference in corrosion of these alloys above and below the melt line.

Aluminium Bolts

          Aluminium Bolts

Tests exposed in boiling acid of Aluminium 5083 Square Bolts, exhibit general corrosion rates in 20 % acid and greater than at higher concentrations. The coolest property of Aluminium 5086 Square Nuts is that it does not allow the formation of precipitates of grain-boundaries on the weld heat affected zone. Because copper and nickel mix readily in the molten state, the useful range of Aluminium 5052 Eye Bolts is not confined within any definite limits.

Aluminium 6063 Eye Nuts has good resistance to oxidation and may be used in continuous service up to 1140 Degree C provided reducing Sulphur gases are not present. Aluminium 7075 T-Bolts is approved for service up to 1230 Degree F, where its melting point is 2615 Degree F – 2635 Degree F. In boiling 45 % magnesium chloride, stressed U-bend specimens of these Aluminium 1100 T-Nuts did not crack in 30 days of exposure.
