Sn99.3cu0.7 Solder Wire

Products Details

The Sn99.3Cu0.7 lead free solder wire is made up of 99.7% tin and 0.7% copper. It is desirable for use in common metal equipment, copper tubes, and copper plates. This product is a conventional type of environmentally-friendly solder by adoption of lead-free soldering technology. Its wire diameter can reach more than 0.2mm.

As a typical type of high-temperature lead free tin wire, our Sn99.3Cu0.7 lead free solder has the melting point of approximately 227 degrees Celsius. It is suitable for both wave soldering and dip soldering processes, which call for environmental protection. During the soldering process, this product features nice liquidity. It can substantially reduce various technical problems, such as bridging, icicle, solder spatter, and more.

This product gives wide applications in the eco-friendly electronics assembly industry. It can be also used to fix the silicone toys.

Chemical Components


The EU RoHS Directive officially took effect on July 1, 2006. It compulsively demands that all electronic products to be sold in the European market must be lead-free products. All Sn99.3Cu0.7 lead-free solder wires made by our company can reach the EU RoHS standards, which can be proved with the above-mentioned product data information.

To Control the Amount of Different Hazardous Substances in Accordance with EU RoHS Standard or Lead-Free Solder Standard:
1. Lead (Pb)
In each kind of homogeneous material, the amount of lead is less than 0.1% by weight.

2. Mercury (Hg)
The amount of mercury in each kind of homogeneous material is less than 0.1% by weight.

3. Cadmium (Cd)
In each homogeneous material, the amount of cadmium is less than 0.01% by weight.

Product Features
1. Favorable Electrical Conductivity
This Sn99.3Cu0.7 lead free solder wire contains 0.7% copper, so the electronic components can produce high electrical resistivity during the soldering process. In particular, it is suitable for the soldering of copper wire and other copperware.

2. High Melting Point
With high fusing point, our product is ideal for the soldering of electronic equipment at high temperature. A combination of tin and copper allows this environmentally-friendly lead free solder wire to have high melting point.
