Each of the metal materials has its pros and cons. So frames made of stainless metal are heavier than other metals, but preferable because they are strong and well know for anti-corrosion properties. Nickel-plated frames made of zinc, copper and nickel itself can cause allergic reactions on the skin and quickly lose their external gloss.
