• Business Description: We are a resource oriented enterprise, service include minor metals and
  
  chemicals, which are mostly rare and precious.
  
  As a newly player, we
  
  have great experience, no matter raw metals or processed chemical
  
  products, and also get an advantageous position.
  
  Our company is located
  
  in Hong Kong, taking advantage of amplified resource from China mainland
  
  at the same time.
  
  The products are based on elements, which is expanded
  
  into many different chemicals for various purpose, as metal element,
  
  oxide, sulphate , chloride, nitrate and so on.
  
  For metal element, it is
  
  not just in lump shape, we also process them into granule, alloy
  
  granule, powder, alloy powder, wire, alloy wire, foil, needle.
  
  It also
  
  could be made upon customer s request.
  
  With long term working
  
  experience, we could guarantee high efficient, good quality, unworried
  
  service.
  
  Hope we are partner of more and more company and realize our
  
  service and value.
