Every WIREOPTIM spool of wire is precision wound via hands-off computerized machines, perfectly tensioned, and handled with care in a clean environment to ensure only the highest quality product lands in your hands. Say goodbye to tangles, oil, skin salts, and other debris or contaminants. Nichrome 80 is an alloy consisting of 80% Nickel, and 20% Chromium. It is ideally suited as a resistance wire heating alloy. It has a high melting point and fantastic resistance to high temperature oxidation. This alloy offers superior service life compared to other Nichrome wire types due to the excellent adhesion properties of its surface oxide. Typical applications include: Industrial: Heating element for furnaces and many consumer appliances like cookers, toasters, kilns, water heaters, flat irons, soldering irons Foam / polystyrene cutting Ceramic working to assist internal support structure Manufacturing of motorcycle silencers Thermocouple positive end Detecting presence of trace metals in flames Specifications: Shape: Round Melting Point: 1400°C Operating Temperature: 900°C Corrosivity: HIGHLY resistant to corrosion Oxidation: HIGHLY resistant to oxidation at room temperature AWG, Diameter(mm), Ohms/ft, Largest Spool Denomination: 16 AWG - 1.29mm - 0.259 - 50' 18 AWG - 1.02mm - 0.418 - 100' 20 AWG - 0.81mm - 0.652 - 50' 22 AWG - 0.64mm - 1.036 - 100' 24 AWG - 0.51mm - 1.64 - 100' 26 AWG - 0.40mm - 2.657 - 250' 28 AWG - 0.32mm - 4.08 - 250' 30 AWG - 0.254mm - 6.76 - 500' 32 AWG - 0.20mm - 10.58 - 1000' 36 AWG - 0.127mm - 26 - 1000' 38 AWG - 0.1007mm - 40.62 - 1000' 40 AWG - 0.0799 mm - 67.63 - 1000' 0.8x0.1mm - 4.15 - 100' 0.5x0.1mm - 6.57 - 100' 0.4x0.1mm - 8.45 - 100'
