As a modern industrial manufacturer, DSN, as we states in our mission, aims to achieve happy life through our achievement and service to the community, while shouldering our social responsibility.  We have been strong advocate for environmental protection; therefore our products use environmental-friendly material, titanium copper.

As a copper alloy containing 2.9% - 3.5% titanium, titanium copper is a highly reliable and high-performance environmental-friendly material.  In particular, at the final stage of alloy making, when processed with ageing temperature, which exerts effects similar to re-calendering, the material is turned to be of harder and stronger quality.  Meanwhile, its conductivity and elongation rate is increased.  This feature greatly conforms to the slim trend of electronic materials. Environmentally friendly copper alloy possesses hardness (1000N/mm^2) and excellent temperature tolerance, achieves desirable minimum bending radius (R/t) and higher folded strength.

We are also put into action in promoting environment awareness amongst our employees by means of setting up used battery recycle stations.  The collected dry batteries, mobile phone batteries and button-cell batteries are sent to recyclers.
