Stainless Steel Foil
A very thin piece of metal or strip. Most metals, and their alloys, can be made into foil. For example, gold, silver, copper, iron, tin, zinc, lead, nickel, aluminum, tungsten,molybdenum, tantalum, niobium, titanium, and steel and stainless steel, nickel and cobalt alloys.
The wide application of foil, for the foil metal and the foil themselves. For example, steel and alloy foils are mainly used in electronic, aerospace, instrumentation and other departments; For the fabrication of miniature high frequency pulse transformers, switching coils, magnetic recorders, magnetic amplifiers, etc. Titanium alloy foil is used to make the decorative mesh on the combustion tube of jet engine, the metal composite heat-proof tile and the titanium multi-layer wall in the heat-proof system of the space shuttle. Tungsten molybdenum foil for special electronic tubes and heating elements; For the production of mechanical strain gauges, precision resistance and recording and video head gap sheets, for the foil of copper nickel and nickel chromium resistance alloys. Stainless steel foil is used to make spacers for high sensitivity pressure elements in precision instruments, main structural materials and heat exchange materials in steam turbine engines, etc. The USES of aluminum foil, lead foil, copper foil and kang copper foil are as follows: aluminum foil production, lead foil production, electrolytic copper foil production and kang copper foil production.
Different countries have different requirements for the thickness limits of different varieties of foil. For example, China has a maximum thickness of 0.20mm for aluminum foil and a maximum thickness of 0.05mm for copper, nickel, lead and zinc steel. The maximum thickness of aluminum foil required by the United States is 0.051mm(0.002"), and the maximum thickness of steel and precision alloy foil is 0.127mm(0.005"). Another measure of foil thickness is the weight per unit area, for example, g/m or oz/fi.
The width of the foil is divided by the user's requirements. However, the wider the manufacturing width, the higher the productivity. The length of the roll body determines the maximum width of the rolling foil. The wider, thinner, and harder the rolled piece, the more difficult it is to roll. The maximum width of rolled aluminum foil is about 2m. A narrow width for steel, titanium, and rare metals. The width of electrolytic copper foil and steamed aluminum foil can reach 2m.
Never be afraid to bother me, it is no matter if you have the regular supplier, just take a consideration while our products are the best price and high quality.
