I have a fully sealed display that is being used in Canada, it works well until real cold weather comes in, at this time it shows some frozen moisture on the inside of the LCD protective polycarbonate.
I have added two different bags of dessicant (silica gel and molecular sieve); they worked...
I have a machined from block explosion proof box made out of 7075 aluminum, I would like to have it cast instead of machined, what kind of alloy will render similar properties to the machined out of stock 7075 aluminum?
