At Micro Metals, quality has always been the foremost priority and to maintain it, we ensure the best practices are executed for its consistent high quality copper metal powder. Starting from quality of raw material till the material is packed and dispatched, we have checks for each of our internal levels. Apart from these checks we have few analysis in place to define the chemical and physical attributes of the copper metal powder. We have divided our analysis in mainly 2 groups being:
The chemical analysis is not conducted within the premises of Micro Metals, rather it is conducted by any prestigious Laboratories in India over our test samples being sent to them, periodically. The analysis includes all the chemical tests for the material, like the purity level of the material, % copper content un-oxidized, % copper content oxidized (generally referred as H2loss) and the % content of Insoluble acid components in the material. Apart from this, the analysis of its shape is also conducted by them; even though it is one of the physical attributes to the material, yet it is included within Chemical Analysis process as per the standards generated by Micro Metal for its manufactured material only.
The rest of the physical analyses are conducted within a laboratory establishment at the Micro Metals premises. This analysis is conducted on each of the batches manufactured in Micro Metals. The batch sizes and related information is confidential to Micro Metals; hence is available for reference purpose for internal use only. This analysis includes the Sieve test (to detail the % separation between the various mesh sizes) and testing the Apparent Density (A.D.) of the batched material. A small sample of each of these batches is retained for a fixed duration for any future reference.
