Depending on the ingot and deep qualified measurement. Parties, not just samples. Without European and Chinese "tricks".
ELECTRICAL CONDUCTIVITY - 104-105% IACS
RRR and HEAT CONDUCTIVITY - are expected / will be 5-10 times higher than similar characteristics of standard grades M0b, M00b and their foreign analogues.
Our measurements of electrical conductivity are 104-105% IACS, possibly RRR ~ 1500 +/- 10%.
Tests for the reflection coefficient at 0-300K are close to theory.
SINGLE-CRYSTAL (not a single crystal, similar to a single crystal )
FORM, DIMENSIONS - ~ to cylindrical, diameter 85-95 mm, height / length 90-150 mm.
For products used in cryogenics and other special fields. Well suited for cooled copper mirrors and other products that require maximum electrical conductivity, thermal conductivity, thermal diffusivity.
Real quality, lots, not just samples, not tons.
