Tungsten & molybdenum parts are easier to be damaged during the shipping especially for some special parts like hot zone parts, heater boat, and big crucibles, if we don't pack them properly.
And the surface of the tungsten and molybdenum products is easier to be oxidized than many other metals.
In order to protect the surface and avoide damage, we will cover the surface of the products by brown paper or film, some times by vacuumize with PP. And then pack properly with wooden box or paper box with foam sheet inside.
