Basic information:
Baoji Tianrui Nonferrous Metal Materials Co., Ltd
Product name:Precision Alloy Square Tube
Baoji Tianrui Nonferrous Metal Materials Co., Ltd mainly produce various specifications and types for 4 J29, 4 J34, 1, 1, 1 J50 J32 J79, 1 J85, 4 J34, 4 J33, 3 J1, 3 j53-serial precision alloy square tube, pipe, plank, strip, great material.
Party pipe and pipe, the precision alloy square tube is my company after several years of research, development and production of the localization of the new material, is currently the only leading domestic production enterprise. The current production craft is mature, the equipment is complete, comprehensive technology, the production batch, stable quality, timely delivery, meet customer requirements. Now use customers at home and abroad has reached more than 30.
4 J29 can cut alloy, English: KOVAR; Translation: can cut, secco tile; China brand for 4 J29 etc brand, this alloy 29% contain nickel, cobalt 17% of hard glass sealing iron base alloy. The alloy in 20 ~ 450 ℃ in the scope of the hard glass with similar expansion coefficient and the corresponding hard glass can effectively sealing matching, and high Curie and good low temperature organization stability, alloy oxidation film density, easy to welding and welding, have the good plasticity, cutting processing, widely used in making electric vacuum components, tube, tube, switch tube, the transistor and sealing plug and relay shell, etc. Can cut easy and molybdenum group coordinate glass sealing, general the surface gold-plated requirements.
