Supply the best High purity bismuth

High purity bismuth  into bismuth oxide minerals calcined, and then with carbon thermal reduction obtained, the available fire refining and electrolytic refining high-purity bismuth. Bismuth is mainly used in the manufacture of fusible alloy, the melting point range is 47 ~~ 262 ° C, the most common alloy of bismuth with lead, tin, antimony, indium and other metal, for fire-fighting devices, automatic sprinkler, boiler safety plug the event of fire, some of the pipes of the piston will "automatically" melt, spewing water. Fire and electrical industry, for the automatic fire extinguishing systems and electrical fuses, solder.

High purity bismuth  alloy solidification shrinkage characteristics for casting printing type and precision casting. Oxygen bismuth carbonate and nitric acid oxygen and bismuth for the treatment of skin damage and gastrointestinal problems. Lead broad applications, such as leaded brass, pigments, lead bullets, and so on, lead-free. However, due to the toxicity of lead, would be a serious the masts human central nervous system, the international community has been seeking to lead alternatives.  High purity bismuth  and lead in many performance aspects are very close, and is harmless to human beings "green metal", bismuth became the preferred material to replace lead.

Zinc tablets is wildly used

Zinc tablets is a widely used coating for the corrosion protection of steel. It is used on stampings, fasteners, and automotive components, providing an excellent base for painting. Zinc is usually provided in a chromated condition, which ranges from blue bright, clear to yellow iridescent, to black. Corrosion resistance is good with the yellow chromates reaching 96 hours neutral salt spray to white corrosion. The new generation of clear, trivalent chromates perform equally as well. Older formulations of clear chromates can be expected to reach 12 hours of salt spray resistance before white corrosion. Red rust remains a function of thickness.


Zinc tablets - widely used to provide protection for steel and other metals.
• Automatic and manual Lines
• Process in alkaline and chloride
• Yellow, clear, black and olive drab chromate

Electrolytic  Zinc tablets  galvanizing is the most widely used electrolytic coating method of steel. This coating process ensures a reasonable protection against corrosion and a pleasant appearance of the products at low cost. Coating is also used to improve the corrosion properties and persistence of paintwork.

The introduction about High purity selenium

There are two main methods for Industrial production of High purity selenium : one is the oxidizing roasting of anode slime and SeO2 distillation, the process will the gaseous SeO2 roasting gas scrubber solution to capture, and then precipitated in acidic media or with lye SO2 role
selenium; another anode slime soda ash sintering in the oxidizing atmosphere, so that selenium into selenium sodium or water-soluble solution of sodium selenate, the process in the sintering conditions, selenium and selenium compounds are oxidized to soluble in water sub- sodium selenate or sodium selenate, and then from the solution by blowing isolated selenium.

High purity selenium is the purity of 99.9999% selenium. Is gray with metallic luster of hexahedral. The relative density of 4.792 ~ 4.86. High purity selenium Melting point 217 ~ 220.5 ℃. The boiling point of 684 ~~ 700 ℃. Chemical properties with ordinary selenium. Conductivity with changes in light intensity, dramatic changes, the use of ion exchange, thermal decomposition of hydrogen selenide, Preparation of sulfite cycle and other methods. Mainly used for the preparation of II - Ⅳ family compound semiconductor, photovoltaic materials, electrostatic photographic and optical instruments, etc.

The advantages about Steel shot

We polish our Steel shot and coat it with a rust inhibitor. This yields a better pellet and costs less than expensive plating. Unlike lead shot, plating does not improve the pellet quality or performance; plating is only for extending shelf life and it adds unnecessary cost.

For pellet size selection and load data see our complete loading manuals The Status of Steel or Advantages. Our steel is annealed to the softest standards. Softer steel is easier on your guns and chokes. 
All Steel shot meets or exceeds all industry standards for softness, consistent shape, and overall quality.

Steel shot is produced by granulation of liquid steel by means of advanced (know-how) method in the medium of protective gas, enabling to produce steel shot with maximum spherical surface and integrity, but with minimum waste of alloying elements in order to give the best operation properties to steel shot, produced by Steel Shot Works:
Maximum abrasiveness of steel shot, which easily achieves surface cleanliness SA3 according to ISO 8501-1;
Minimum processing time due to the high abrasiveness (reduction of energy consumption, economy of the working hours spent for repair of shot-blasting machine, filters economy etc.)
