brrb Resettable fuse: Analysis on the material of the fuse
What is the material of the fuse? I believe this is a question that many friends are confused about. Today, Shenzhen Jidentong experts explained: The fuse must be an easily fusible metal wire, so that it can melt in time when the current is too large, thus playing a protective role. .
Therefore, we generally use lead-antimony alloy wire as the material of fuses.
The fuse material is mainly made of alloys with relatively high melting points such as aluminum antimony alloy. The main element of the aluminum-magnesium alloy aluminum plate is aluminum, and some magnesium metal or other metal materials are added to strengthen its hardness.
It is an aluminum alloy that mainly adds elements. Because of its good corrosion resistance, it is also called rust-proof aluminum alloy. Because it is metal itself, its thermal conductivity is very good. The intensity is also quite outstanding.
Aluminum-magnesium alloy aluminum plates are strong, lightweight, low-density, good in heat dissipation, and strong in pressure resistance. They can fully meet the requirements of highly integrated, light and thin, miniaturized, anti-fall, electromagnetic shielding and heat dissipation products. Require. Its hardness is several times that of traditional plastic cases, but its weight is only one-third of the latter.
