Best Speciality Nickel Alloy Manufacturer JLC Electromet Pvt. Ltd. is one of the world's leading manufacturers of Nickel and Nickel based Specialty Alloys in wire, rod, strip and ribbon forms.

Ni

Ni-Resist is suitable in these applications because its ductility, hot strength and low coefficient of thermal expansion provide best resistance to such severe thermal shocks. Physical properties depend on operating temperatures and the exact nickel composition of the SG iron alloy.

Ni Resist castings, Investment Casting

Ni Resist castings can be specified in either a Grey Iron base material or a SG Iron based material. These materials have been developed to offer good resistance to sea water and alkaline corrosion, scaling resistance, thermal expansion, frictional wear, oxidation, structural stability, cryogenic applications and erosion.

The Effect of Inoculation on Properties of Modified

In this study, ductile Ni-resist alloy with a minimum 18 wt. % nickel composition was modified. Up to 12 wt. % manganese was added together with 10 wt. % nickel before undergoing the inoculation process at various percentages to investigate the effects of the alloying elements on both its microstructure and mechanical properties..

High Si

1998/3/1A wide variety of available materials are used in exhaust manifolds, and high Si-Mo falls between ductile iron (D4512) and Ni-Resist in terms of durability and cost. In 1977 Chrysler Corp. began switching from gray to ductile iron manifolds because ductile iron manifolds are more durable in general purpose applications.
