History of discovery
Precision alloys opened a new era in instrumentation and electrical engineering. The first of the precision alloys was discovered by the Swiss scientist-metallurgist Sh. Guillaume in 1896. In 1920, he received the Nobel Prize in Physics for the discovery of this important alloy, so necessary in precision instrumentation. Nichrome was opened in 1905. More than half a century, he was indispensable in electrical engineering. Alloy fechral is designed as a cheaper analog of nichrome in connection with the need to reduce the cost of production. This alloy is distinguished by high corrosion resistance, combines high t ° melting and considerable electrical resistance: up to 1.3 ohm • mm2 / m ,. Due to the use of inexpensive aluminum instead of nickel, the cost of production is reduced by 6 times compared with nichrome.
