The metal recycling industry encompasses a wide range of metals. The more frequently recycled metals are scrap steel, iron (ISS), lead, aluminium, copper, stainless steel and zinc. There are two main categories of metals: ferrous and non-ferrous. Metals which contain iron in them are known as ferrous. Metals without iron are non-ferrous.


 Precious metals metals with a high market value in any form, such as gold, silver, and platinum group metals.

Exotic metals contain rare elements such as cobalt, mercury, titanium, tungsten, arsenic, beryllium, bismuth, cerium, cadmium, niobium, indium, gallium, germanium, lithium, selenium, tantalum, tellurium, vanadium, and zirconium. 

is a chemical element with symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge, and it belongs to the transition metals and is hard and ductile.


Recycling is an important factor in nickel's life cycle and an important contributor to global sustainability. Nickel-containing products, such as stainless steel, are durable and are designed for long-term use. Demand for recycled nickel is growing; it is part of the solution as a complement to primary production.


A superalloy, or high-performance alloy, is an alloy with the ability to operate at a high fraction of its melting point. Several key characteristics of a superalloy are excellent mechanical strength, resistance to thermal creep deformation, good surface stability, and resistance to corrosion or oxidation.


Superalloys are the most complex nickel-base alloys, often containing 10 or more constituent components. Compositions of some typical superalloys are listed in Table 1. These alloys are usually based on nickel–chromium. Added alloying elements include the refractory metals such as tungsten and molybdenum for solid-solution strengthening. Cobalt enhances strength as well as oxidation and hot corrosion resistance. Aluminum and titanium promote the formation of the major strengthening gamma-prime, γ′, phase. Superalloys typically contain between 15 and 60% of this strengthening phase. Niobium contributes to the formation of the precipitate gamma double-prime, γ″; this phase is the primary strengthening phase in alloys such as alloy 718.



Around 68% of all nickel available from consumer products is recycled and begins a new life cycle (reference year 2010); another 15% enters the carbon steel loop. However, around 17% still ends up in landfill, mainly in metal goods and in waste electrical and electronic equipmentalloys and Inconel solids, turnings, chips, powder, grindings, grinding sludge. Monel Scrap: We recycle all Monel alloys—400, 401, 404, K-500 and R-406—and in any form including Monel turnings, solids, chips, grindings, and powder. Hastelloy Scrap: We recycle Hastelloy scrap in any form—turnings, chips, grindings, solids and powder—and all Hastelloy alloys: Rene Scrap. Other: Waspalloy, Udimet 500. etc.
