Silver prices increased 45.4% last year and silver investments during the first week of 2021 rose 90% compared to the first seven days of 2020. That’s bad news for industrial buyers, many of whom are now looking for alternative materials. Nickel-aluminum silicones can combine EMI shielding with other performance properties, but engineers need to see the test data before switching [...]
