Description: These iron tips are made of electroplated iron and nickel which protects them from rusting, and they feature heat resistance up to 480℃ and a lifespan of over 20,000 solder joints with proper use. for a craft job, for example, on a car problem, once the micro switch popped out of the tiny PCB, you noticed that the micro switch contacts are smaller than the micro (smaller than a pin head), or soldering in a narrow space also to reform the tin bridge: emerging from the soldering of the chips. Specification: Material: Copper: Color: Silver: Plating: Iron & Nickel (Finish): Outer Diameter: Approx. 6.7mm/0.26": Inner Diameter: Approx. 4.0mm/0.16": Length: Approx. 43cm/16.93": Package Weight: approx.47g: Model: 900M-TI: Applicable to: 936, 937, etc.: Temperature range: 200-480℃: Quantity: 10pcs/bag 1. Made of high quality oxygen-free copper, fast conductance and heat resistance up to 480℃ for durable use 2. Applicable to 936, 937, etc. soldering stations. With its needle-like pointed end which is suitable for DIY crafts, for example, fits car alarm holder, such as micro switch which had been chipped off the small circuit board and contacts for 3. If used properly, its lifespan can reach more than 20,000 solder joints 4. It has the advantage of long life and not easy to rust, easy to install and use 5. It has high safety and stable performance. Very easy to carry and clean. Use the sponge to polish the surface. Wrap them in cans.
