However, if you do not have any metal allergies, any type of zinc alloy jewelry should be safe to wear. As noted earlier, zinc alloy contains several elements, including nickel, lead, copper, and nickel-copper. Nickel is a common cause of allergic reactions in many people while lead is toxic as it can cause lead poisoning to the wearer. Types include chromium nickel steel where chromium is >17% and >7% nickel (there are exceptions to this rule.) *Values that are single indicates the maximum % unless it is stated differently. Unless notes, other elements of all alloys listed include a maximum content of 2.0% MN, 1.0% Si, .045% P and .03% S, The balance if Fe. Nickel is an element and a material added by various mods. As added by Vanilla Main article: Nickel on the Minecraft Wiki As added by Embers Nickel spawns as an ore between Y=0 and Y=24. As added by Extra Bees The Lustered Bees produce Nickel Comb which produce Nickel Grains when processed in a Centrifuge. As added by Factory Tech Spawns as an ore between Y=0 and Y=24 As added by GregTech 5 These chromium-nickel alloys can contain 20-80% nickel, with some able to resist oxidation and retain their shape at temperatures up to 1250°C (2280°F). Low thermal expansion nickel-iron alloys, containing 36-42% nickel (for example Invar® (UNS K93600)), have long been used in bimetallic strips for thermostats and other temperature control Except pure nickel, the nickel based alloys for chemical processing applications are significantly stronger than SS 300 series. Nickel alloys also have excellent ductility and hardness. Nickel alloys have completely austenitic microstructures. Almost all grades used in the chemical industry are solid solution strengthened. Nickel also reduces thermal expansion for better dimensional stability. Nickel is the base element for superalloys. These metals have excellent resistance to thermal creep deformation and retain their stiffness, strength, toughness and dimensional stability at temperatures much higher than the other aerospace structural materials. The simplest steels are iron (Fe) alloyed with carbon (C) (about 0.1% to 1%, depending on type) and nothing else (excepting negligible traces via slight impurities); these are called carbon steels. However, the term "alloy steel" is the standard term referring to steels with other alloying elements added deliberately in addition to the carbon. Aluminum alloys do corrode, but when water comes into contact with the metallic surface, it develops a protective coating called 'aluminum alloy oxide' which makes it more corrosion resistant. Magnesium is prone to corrosion (especially galvanic corrosion), which appears as a grey layer on the surface. Out of all metallic alloys, magnesium lVTS.
