About SAC 305 Alloy

SAC 305 Alloy is one of the most widely used lead-free solders in the electronics industry and has become the standard choice in many manufacturing environments. Containing 96.5% tin, 3% silver, and 0.5% copper, this alloy delivers a strong balance between reliability, flow characteristics, and cost-effectiveness. The addition of silver provides improved wetting properties, while copper helps reduce dissolution of base metals, making SAC305 extremely versatile for a wide range of soldering applications.

Applications of SAC 305 Alloy

SAC305 is used across industries including automotive electronics, consumer electronics, telecommunications, and aerospace. Its consistent performance ensures stable solder joints in demanding environments. This alloy is particularly well-suited for:

Many manufacturers choose SAC305 as their first lead-free alternative when transitioning away from traditional tin-lead solders, thanks to its proven track record of mechanical strength and thermal fatigue resistance.
