Mandrel bar plays a crucial role in producing large diameter seamless pipes in modern industries. In production line, it have to bear strong and complicate stretch, compressing touching stress and high temperature cold-hot yield stress under high speed cycling. Under these circumstance, chemical components, mechanical propertied, no-metallic inclusion, grain size, microstructure, ultrasonic test, size precision, surface finish, all these factories of steel are required very strictly. Mandrel bar is made from H13(4Cr5MoSiV1),
With annual output of 15 thousand tons, its quality and service life have reached to world level of that. Our company is capable of producing a series of mandrel, such as MPM, PQF, FQM, with the diameter of 80~350mm, the length of 2500-17500mm.
Equipment advantage: steel making (EBT+LF(VD)+ESR)-forging(formed by hydraulic press machine + forged by rotary forging machine)-annealing-rough machining ¨Cmagnetic test-heat treatment-ultrasonic test-finish machining-chrome plating-thread phosphating.
Our products include various rare metals products in form of plate, bar, rod, wire, pipe, crucible, sputtering target, machining part, and heat elements, and corrosion-resistance parts as well.

We are a manufacturer and exporter specialized in producing copper powder including water atomized pure copper powder, brass powder (CuZn30, CuZn20), bronze powder (CuSn10, CuSn13) and copper alloy powder (CuPb10Sn10, CuPb30, CuPb24Sn1, CuPb3Sn6Zn6, CuPb7Sn7Zn3, CuSn6.5P0.3 etc.)
Aluminum alloying tablets are used to adjust the content of metallic element in the manufacture of high quality aluminum alloys, providing the following benefits:
- high element recovery rate (typically over 95%)
- rapid dissolution at normal casthouse operating temperatures
- accurate and clean addition
- concentrated form means reduced inventory, transport and storage costs.
Two or three tablets wrapped directly by aluminum foil.
20kgs in a cardboard.
Application
AlTiB produces an equiaxed fine grain structure in cast Aluminum Alloys, providing the following benefits:
-Improved homogeneity
-Uniform distribution of elements
-Elimination of hot tearing
-Enhanced response to heat treatment
-Superior mechanical properties
-Increased machine ability.
Size Available in the form of:
1. Cut rod: diameter 9.5mm length: 10¡ª1000mm
2. Coil: 180kgs/coil
3. Small ingot: 250g/pc
Also can produce as per customer require.
Barrel forms the main part of dart. Tungsten is a very dense material, so tungsten dart can be made quite slim as to give user a safe and easy grip. Commonly, the barrel material is tungsten based heavy alloy billet. At xiamen eternal tungsten, we can make w-ni-fe barrel, w-ni-cu barrel, w-ni-cu-fe barrel, etc for tungsten dart. Also, we can make products according to customer demand.
Alloy with high and stable resistance, corrosion resistance, surface oxidation resistance is good, a better under high temperature and seismic strength, good ductility, good workability and weldability, is widely used in industrial electric furnace, metallurgy, household appliances, machinery manufacturing, heating element and resistor varistor other material.
