Tungsten copper sheet is composed of 50% tungsten and 50% copper, combining tungsten's high melting point and strength with copper's excellent electrical and thermal conductivity. 

Tungsten-copper parts are made from high-performance tungsten-copper alloy, combining tungsten’s high melting point and strength with copper’s excellent electrical and thermal conductivity. 

Silver tungsten rod is a high-performance metal composite material composed of 60% tungsten and 40% silver. 

Tungsten-copper heat sinks are composite materials that combine high thermal conductivity with a low coefficient of thermal expansion. 

According to 'GB/T 26033-2010 Ammonium Metatungstate', during the transportation of ammonium metatungstate, it is necessary to take care to prevent moisture and avoid severe collisions. The product shall be stored in a dry, ventilated place free from acidic or alkaline atmosphere. From the date of receiving the product, the storage period for spray - dried material shall not exceed six months, and that for crystalline material shall not exceed one month.

According to 'GB/T 26033-2010 Ammonium Metatungstate', ammonium metatungstate is generally packaged in iron drums, lined with polyethylene plastic bags for sealing. If there are special requirements for packaging, they shall be determined through negotiation between the supplier and the buyer. The weight of each package shall also be determined through negotiation between the supplier and the buyer.

According to 'GB/T 26033-2010 Ammonium Metatungstate', the appearance quality standard for ammonium metatungstate is that the product appears as a white powder or light yellow crystals, with no visible foreign matter or lumps upon visual inspection.

According to 'GB/T 26033-2010 Ammonium Metatungstate', the pH standard for ammonium metatungstate is that, at room temperature, the pH value measured with a solution containing 650g/L of tungsten trioxide does not exceed 4.5.

According to 'GB/T 26033-2010 Ammonium Metatungstate', the standard for water-insoluble substances in ammonium metatungstate is that, at room temperature, the water-insoluble substances measured with a solution containing 650g/L of tungsten trioxide do not exceed 0.05%.
