Beryllium Copper (Be-Cu)

WebbBerylliumoxid (BeO) är ett oorganiskt ämne med den kemiska formeln BeO. Detta fasta, vita kristallina ämne är noterbart då det är en elektrisk isolator som leder värme bättre än någon annan icke-metall förutom diamant, det leder till och med värme bättre än många metaller. [1] Dess höga smältpunkt har lett till att det använts som refraktiskt material. WebbBeryllium does not form any compounds with aluminum. Instead, it forms a series of alloys whose melting points vary from the melting point of Be (1283 °C) to that of Al (654 °C). However, the melting point line of Be 1-x Al x is not linear but is an “s-shaped” curve as shown in the following diagram. body sculpture treadmill bt3152 https://pineleric.com
