Tungsten alloy properties are sensitive to impurity substances, atmosphere and cooling velocity. Impurity substances such as P, S or others segregating on grain boundary will descend anchoring strength on interface so that descend tungsten alloy properties. Improper control of cooling velocity will produce mesophase or make impurity substances segregate on grain boundary.
So, thermal treatment is necessary for sintered tungsten alloy to improve sintered tungsten alloy properties. Thermal treatment contains quenching, rapid cooling, dehydrogenation in atmosphere and surface hardening. It aims at descending the segregation of impurity substances on interface and hydrogen embrittlement, improving tungsten alloy properties or satisfying the requirements for other properties. Utilizing thermal treatment can eliminate hydrogen embrittlement and phosphorous embrittlement, decreasing the segregation of impurity substances on interface and improving boundary strength of tungsten alloy. That will improve strength and elongation of tungsten alloy.

Density: the density of tungsten alloy radiation shielding is almost 18.6g/cm3 while lead is only 11.34g/cm3, so at the same weights high density heavy alloy can provide the same energy absorption as lead using 1/3 less material. When the weight is certain, more density, and the thickness would be thinner. Tungsten alloy material could be made with thinner thickness but high absorption of radiation in high density. That is why tungsten alloy material is suitable for radiation shielding.
Environmental protection: tungsten alloy radiation shielding is less harmful to our health than lead material of radiation shielding; this is because lead is poisonous and is not good both to our body and the environment, so tungsten alloy is environmental friendly material.

Compared with traditional radiation shielding material, tungsten alloy radiation cans provide higher radiation absorption. The absorptive capacity of the high-density tungsten alloy is three times than that of lead! And lead, the use of high-density tungsten alloy radiation cans also can help you reduce administration costs, because you do not need to obtain special permits.
Tungsten alloy radiation cans are very popular with our daily uses both in medical and industry.

The type of container used and the safety precautions put in place during transport depend on the type and the amount of nuclear material being transported. For small amounts of nuclear materials which have short half-lives and very low levels of radioactivity, all that is needed is a simple tungsten alloy cardboard box.
For larger amounts of highly radioactive nuclear material such as used nuclear fuel, tungsten alloy cardboard box has been developed capable of remaining intact during and after catastrophic accidents such as being hit by a train (as shown on the right, being in a fire or being submerged in water.

Tungsten rubber slice is combined by tungsten powder and raw flexible magnets through sheet metal technology, all kinds of tungsten rubber slice can be machined according to different uses and requirements.
Tungsten rubber slice has the properties of tungsten and rubber, such as high density, good radiation resistance, easily machined into different types of products, low cost, good ductility, etc. the most important point is that tungsten rubber slice is non-toxic and environmentally friendly, so tungsten rubber slice is the first choice to be the substitute of lead slice and tungsten rubber slice is the best material to make into radiation shielding.
