general characteristics

Precision alloys have a few physical and technical qualities (thermal, elastic, magnetic, electrical), due to the balanced composition, manufacture and processing of care, lack of contaminants. This group includes complex alloys based on iron and nickel. Melting temperature — about 1450 ° C.

Relevance

56DGNH brand alloy refers to a high-precision materials with a minimum coefficient of thermal linear expansion. Used in the field of innovative instrumentation, for the production of precision electronic sensors, consumer and laser technology, metrology and measurement devices. Alloy forms the basis of sensitive elements with precision dimensions unchanged in the range of climatic temperatures. The minimum coefficient of linear expansion can be used for the manufacture of alloy standards of length measures in charge of complex shapes, tight junctions of the glass or mica.
