1) tungsten, molybdenum and their alloys. Which we called powder metallurgy metal or refractory metal. Since tungsten and molybdenum has very high melt point, so it can not use the conventional casting process to produce it. HOSOMETAL’s powder metallurgy process:
In the procedure of powder metallurgy, powder mix, pressing and sintering are three key factors to guarantee quality. We, HOSOMETAL has rich experiences in all process router and we can adjust and optimize process according to clients’ demanding.
2) CuCrlZr, CuCr, ODSC, CuBe, CuCoBe, CuNiBe, and CuSiNi which is the special copper alloy major used as the resistance spot welding electrode.

Electrical and power electrode
we make the electrical contact with copper tungsten(CuW), silver tungsten(AgW), copper tungsten carbide(CuWC), and silver tungsten carbide(AgWC).
from the material to the final parts we supply one stop service.
HOSOMETAL supply the copper tungsten heat sink and heat management device.
Electronic packaging is to put a certain function of the integrated circuit chips (including semiconductor integrated circuit chips, thin film integrated circuit substrate, hybrid integrated circuit chips) placed in a corresponding shell container, which can provide a stable environment to protect chips work normally and keep stable functions in integrated circuit. At the same time, encapsulation also is connection method of outputting and inputting to make the transition to outside, and it can form a completed entirety with chips. Electronic packaging material are requested certain mechanical strength, good electrical properties, thermal properties and chemical stability. According to the different type of integrated circuit and practical place, we choose different packaging structure and materials.
We produce the good proportion consistency of counter weight and we have a variety of materials tungsten copper, tungsten copper nickel, tungsten nickel iron to choose. At the same time, we possess certain mechanical processing capacity, and we can produce finished parts according to customer’s drawings.
Counterweight parts are used to increase its weight to balance the weight. Balance weight block can be made to swing, weight transfer, imbalances and vibration situation to make up. It forms or changes the center of gravity to ensure the best balance. Balance weight block is a key component in many different applications. It helps to reduce parts on the load, so as to prolong the service life of parts.
Application case is as follows:
Aerospace: propeller and helicopter blades automobile industry: crankshaft counterweight and chassis counter weight Watchmaking: pendulum clocks rotor Sports equipment: golf clubs Optical industry: microscopes and measuring instruments Narrow space placed the heavier elements
We produce the density of material up to 18.89 g/cm³, so when we need to put heavier elements into narrow space, our w-base high proportion alloy performance shows superior performance
HOSOCP resistance welding product introduce
HOSO Metal can produce spot welding electrode, seam welding wheel, projection welding electrode, submerge arc contact tips…from the metal alloy manufacture to the finished welding electrode, HOSO Metal provide the one stop service to our customer.
Good performance resistance welding electrode should following below two principle
reasonable electrode design
choice the right metal alloy
tips for reasonable electrode design:
Over heat possible reason
The risk of over heat
Unreasonable electrode design
Work piece distortion, crack
Use DOE simulate heat behave
Welding parameter setting incorrect
Electrode top deformation
Adjust the parameter setting
Cooling system design incorrect
Work piece’s metal or plating layer stick the electrode
Choice right material or use the combine electrode design
Electrode life time reduce
Improve the cooling system
Moldmaking and tooling
Mold is used for molding item tool, which is composted to all kind of parts. Different moulds made up to different parts. It is mainly by the changes of the molding material physical state to implement items shape processing. In mould industry production, we produce all kind of mould and tool of needed products by injection molding, blow molding, extrusion, die casting or forging molding, smelting, punching, stretching methods.
we supply the below product for the EDM molding application:
EDM die sink copper tungsten electrode:
EDM small hole drilling electrode:
we also make below electrode for the EDMing:
tungsten copper electrode with shank
chromium copper square bar
PCD tools disk erosion copper tungsten electrode
tungsten copper thread electrode，etc
hot runner nozzle nozzle
