Stainless steel foil 0.002mm

Use of stainless steel foil 

Application of stainless steel foil in the electronics industry 

Shrapnel spring type: The contact shrapnel type uses stainless steel, which is then plated with chromium or nickel to improve conductivity and tinning performance. Common materials include SUS301 and SUS304, with thicknesses of 0.15 and 0.2. 

Support frame: In the injection molding process of plastic parts, stainless steel parts are first placed in the mold and fixed before being injected, which is used to improve the strength and shielding effect of the back shell. 

Appearance parts: stainless steel front shell and battery cover, made of SUS316L with a thickness of 0.5. 

Reinforced steel sheet: In piano keys and side keys, stainless steel sheets are used as intermediate pieces to ensure the flatness of the keyboard, and can also be used for grounding, shielding, and shading. 

Stylus sleeve: generally made of SUS304 material with a thickness of 0.2. 

PIFA antenna: SUS301 or 302 can also be used as PIFA antenna, with a material thickness of 0.2. 

Application of stainless steel foil in the battery industry 

Lithium battery outer packaging and current collector: stainless steel foil, used for the entire machine and negative electrode. If the negative active material uses silicon alloy that can achieve high capacitance, stainless steel foil with higher strength is expected to replace the original copper foil. 

Application of stainless steel foil in other industries 

Precision electronics: stainless steel foil is used to make force strain gauges, precision resistors, and recording and video head gap plates. 

Mechanical manufacturing: Stainless steel foil is used to make pressure vessels and spacers on high-sensitivity pressure components in precision instruments. 

Metal products: Stainless steel foil is used to make high-strength structural materials and heat exchange materials.
