On November 27th, 1952, Ministry of Heavy Industry prepared
to construct the Industrial Experiment Institute of Non-ferrous
Metals, which was one of the three biggest Experiment institutes
of national integrated industry (including steel, non-ferrous
and chemistry industry).
＃ In 1957, begun the
research on titanium and titanium alloy, and in 1958, the
first titanium ingot free of tungsten impurity was smelted
successfully.
 ＃
In January 1958, the Industrial Experiment Institute of Non-ferrous
Metals was renamed as the General Institute of Non-ferrous
Metals, Ministry of Metallurgy.
＃ From 1958 to 1964,
the separation and extraction processes for sixty-four elements
in the Elementary Periodic Table have been achieved, which
ensured the development of the non-ferrous metals industry
in China.
＃ In 1964, fulfilled
the trial-manufacturing of sixty-six new precious metal products,
and from 1965 to 1967, completed the trial-production of more
than one hundred new precious metal products.
＃ In 1979, begun the
research of composite contact material with precious metals,
and in 1985, a production line of silver-copper composite
rivet contact was introduced, which achieved an annual output
of ten tons.
＃ In 1983, begun the
research of precious metal powder and electronic paste.

＃ In September, 1992, the
Rare and Precious Metal Materials Research Institute was established.
＃ On October 18th of 2000,
Grikin Advanced Materials Co. Ltd set up.
＃ In August, 2003, new
manufacturing facility in Changping Science Park was brought
into use.
＃ On June 1, 2004, attested
