Alloys have the following properties:

The melting point of any of the constituent metals is higher than the melting point of most alloys.

One of its defining characteristics is its exceptional hardness, which surpasses that of any metal found within its components.

The alloy exhibits inferior electrical and thermal conductivity when compared to each of its individual component metals.

Alloys possess the remarkable ability to give rise to materials with exceptional properties such as high resistance and thermal resistance. Additionally, these alloys exhibit excellent formability, making them highly versatile in various manufacturing processes. They are also well-suited for hot dip tin, welding, and plating applications, showcasing their exceptional properties in these areas. Furthermore, alloys display commendable corrosion resistance and are not prone to stress cracking corrosion. With a balanced strength and good conductivity, these materials offer a unique combination of mechanical and electrical properties.

The electronic and communication industry extensively utilizes tinned copper wire, leading to the generation of a significant amount of waste tinned copper wire during production and usage. Proper handling of this waste tinned copper wire is crucial, as a portion of it is reused in the production of bronze alloy while the rest requires the removal of the tin layer from the copper wire for other purposes. Hence, it is imperative to select an appropriate detinning process that involves minimal investment, easy operation, achieves a good detinning effect, and results in minimal copper loss.

Lead-free welding technology can replace the use of lead in the welding process. The selection of lead-free welding materials depends on the specific welding equipment being used. For hand welding, a combination of tin-copper alloy, tin-silver alloy, or tin-silver-copper alloy is commonly employed. Dip welding and wave welding can utilize tin-copper alloy, while reflow welding can be achieved with either tin-silver alloy or tin-silver-copper alloy.

When it comes to the electronics industry, copper alloy is an incredibly versatile material that is both economical and efficient. Thanks to its outstanding strength, electrical conductivity, and thermal conductivity, copper alloy has become a staple of lead frame fabrication. This material also boasts excellent processing capabilities, allowing it to be shaped and molded with ease. Furthermore, needle welding is a breeze with copper alloy, and it possesses a high level of resistance to corrosion, making it an ideal choice for long-term use. By alloying copper, its performance can be fine-tuned to meet an extensive range of requirements, ensuring that it performs optimally in various applications. For these reasons, copper alloy is currently the most commonly used material in microelectronic devices, playing a vital role in their functionality.

Tin copper alloy wire can be processed and derived from a variety of cables, such as power cables, communication cables, control cables, special cables, these cables are widely used in power, railway, communications, aviation, medical, transportation, construction, ships and other industries.

In terms of physical properties, tin-copper alloy wire has good electrical conductivity, thermal conductivity, high strength, corrosion resistance, high temperature stability.

Quality and control standards meet BS EN13601 ASTM B846 ASTM B624 American standard ASTM B105/624, European standard (EN13602), Japanese standard (JIS H3260), DIN CEN/TS 13388, BS EN 50149, GB/T 5231, GB/T 21652, etc.

After the completion of the production of tin copper alloy must be strictly in accordance with the customer and industry standards for packaging, storage, handling and transportation, to ensure that the product is not damp, not hurt.

During the transportation of the product, take protective measures such as moisture proof (wrap the product with four square plastic bags on rainy days), anti-bruise (fix the product with a wooden frame to prevent the product from rolling and bruise), and each delivery is delivered at the scheduled time.

Storage conditions of finished products at ambient temperature ≤35℃, relative humidity ≤65%. (The storage life of the conductor must meet the requirements of temperature and humidity)
