Tungsten Powder Cost Keep Rising
As of Wednesday, this week tungsten product price of 65 degrees black tungsten concentrate 7.5-77 million / ton, APT11.5-11.7 Million tons of tungsten powder 180-182 yuan / kg, tungsten carbide powder 178-180 yuan / kg, tungsten iron (FeW80) 12.2-125 million / base tons, tungsten iron (FeW70) 11.5-11.7 million / base Ton, sodium tungstate 8.4-87 million / ton. Ring last week, a variety of tungsten products prices are one thousand yuan to three thousand yuan per ton ranging from rising. Due to the increase in tungsten concentrate prices and reluctant sellers, APT and tungsten powder, tungsten carbide powder prices rose faster, tungsten and sodium tungstate products relative to the relatively small increase, which is its production scale and downstream demand constraints. This week, the rapid increase in the market price of tungsten, on the one hand after the holiday part of the replenishment to pick up, on the one hand is the guide price and large business long single support, it is learned that a large Tungsten in Jiangxi Province in February the second half of the purchase of long single The price of 65 degrees black tungsten concentrate 75,000 yuan / ton, 65 degrees of white tungsten concentrate 73,000 yuan...
Effect and Application Range of Thermal Sprayed Alloy Powder
Thermal spraying is a kind of surface strengthening technology, which has always been a new technology project promoted by our country. It uses electric arc, plasma arc, gas-oxygen and other forms of heat source, the metal or non-metallic materials heated to melt or semi-molten state, and in the high-speed airflow atomized into fine droplets or high temperature particles to high Of the jet speed jet to the treated surface of the workpiece, the formation of a solid cover, so that the workpiece surface with different hardness, wear resistance, corrosion resistance, heat resistance, oxidation resistance, insulation, insulation, electrical conductivity, sealing, disinfection, anti-microwave Radiation and a variety of other special physicochemical properties. It can be repaired in the maintenance of equipment waste, so that scrapped parts “back to life”; also in the manufacture of new products to strengthen and pre-protection, so that “longevity.”
Plastic spraying technology features
6, a wide range of applications Wide use of plastic spraying can be in the steel, cast iron, copper or aluminum and other metal workpiece surface, the thickness of 0.1-0.5 mm coating can be used for dynamic fit, static fit or seal and leakproof, anti-corrosion effect The occasion 7, excellent performance of the spray coating The impact strength, shear strength, toughness, fatigue resistance of repeated deformation of the plastic spray coating are better than the epoxy adhesive. Plastic coating corrosion resistance is good, the general metal can not match. It also has good sound absorption, thermal insulation and electrical insulation properties, can be used in a variety of special requirements of the occasion. Plastic spray coating has excellent machinability, can carry out various forms of machining. Spraying plastic spray finish up to spend 8, when the smooth finish up to spend 12 flowers. Therefore, the size and geometry of the workpiece are easy to guarantee. In addition, if various modified materials are added to the plastic sprayed coating, the physical and mechanical properties of one aspect of the sprayed coating, such as increasing the strength, increasing the wear resistance, increasing the thermal conductivity and the like, are remarkably improved. 8,...
TiC-based steel-bonded cemented carbide characteristic
TiC-based steel-bonded cemented carbide can be combined with high manganese steel stope stability,with good tissue compatibility, has a unique performance,can form a matrix will not fall off.Inlaid TiC-based cemented carbide high manganese steel castings,wear resistance can be significantly improved in different working conditions,at least can be increased by 2 times,up to 5 times.

Titanium carbide based carbide customer feedback
In our sales process, many customers often ask, your titanium-based steel can not do with a higher hardness, so that our high manganese steel wear parts, such as crusher hammer, plate hammer life Will be longer. In fact, we can adjust the formula so that the hardness of the alloy rods is higher, but the application should pay attention to some technical points: for example, Langfeng materials produced titanium alloy steel rod hardness can not be higher than HRC62, HRC60 best, because it and High manganese steel substrate, there is a feature, in a strong impact, extrusion conditions, the surface of the rapid occurrence of hardening phenomenon, so that while maintaining toughness and plasticity at the same time hardening layer has good wear resistance.
Powder metallurgy technology prospects
Powder metallurgy is a very promising new technology, new technology, has been widely used in agricultural machinery, automotive, machine tools, metallurgy, chemical, light industry, geological exploration, transportation and other areas. Powder metallurgy materials are tool materials and mechanical parts and structural materials. Tool materials are roughly powder high-speed steel, carbide, superhard materials, ceramic tool materials and composite materials. Mechanical parts and structural materials are powder friction reduction materials, including porous anti-friction materials and compact anti-friction materials; powder metallurgy iron-based parts and powder metallurgy non-ferrous metal parts.

Zhejiang customers visit TM52 titanium carbide rods
Customers in the company’s leadership and technical staff, accompanied by a visit to the bar production workshop to understand the production process, the company’s production workshop and products have given a high evaluation of the affirmation of the Changsha-lang Metal Materials Co., Ltd. in the domestic high-speed processing tool Materials, manufacturers in the field of leading position, the current supply and demand sides of the business negotiations are further underway.
Spray plastic materials and modified materials
In plastic spraying, to improve the physical, mechanical, chemical and optical properties of plastic spray coating and change the color of the material, called the modified material. Often modified materials generally known as the filler. A wide range of modified materials, a modified material can often play several roles, the purpose can be used to highlight one of the role. Such as graphite, tungsten disulfide, aluminum, copper, glass, quartz powder, pigments, mica and other modified materials.
