About 79,300 tons of nickel was improved from purchased scrap in 2006. This represent about 35% of reported secondary plus apparent primary consumption for the year.
With few exceptions, substitutes for nickel would result in bigger cost or a tradeoff in performance of the product. Aluminum, coated steels, plain chromium steels, and plastics can restore stainless steel to a limited extent in many building and transportation applications. Nickel-free specialty steels are occasionally used in place of stainless steel within the power generating, petrochemical, and petroleum industries. Titanium alloys or specialty plastics can alternate for nickel metal or nickel-base alloys in highly corrosive chemical environments. Recent cost savings in manufacturing lithium ion batteries allow them to compete against NiMH in certain applications.
Identified land-based resources averaging 1% nickel or better contain at least 130 million tons of nickel. About 60% is in laterites and 40% in sulfide deposits. In addition, extensive deep-sea resources of nickel are in manganese crusts and nodules covering large areas of the ocean floor, particularly in the Pacific Ocean.
