Our target material products used in metal film resistors include ultra-low resistance serials, low resistance serials, mid resistance serials and high resistance serials. The composition of this kind material was scientifically designed, and the products have smooth surfaces, excellent electronic conduction. With stable work electricity current and strong bonding with the foundation board, the quality of the target materials is comparable to that of America and Japan. The resistors yielded by the target materials have narrow resistance value range, high stability, excellent heat-resistance, wearing resistance, oxidation-resistance properties and small temperature coefficient of resistance. Our products accord with the national standard GB587386, and mid and low resistance target materials have passed the technical appraisal by Ministry of Metallurgical Industry and Ministry of Mechanical Electronics. The products have owned the third science and technology progress award of Zhejian province, and granted a national invention patent.
