Why does the fall arrester use aluminum cover

In addition to polypropylene housing, the fall arrester is more aluminum housing. What are the advantages of aluminum housing for fall arrester?

① Compared with other metals, the aluminum shell has a smaller density and lighter weight, which increases the portability of the aluminum shell arrester to a certain extent.

② Aluminum has good casting performance and strong plasticity, which has good advantages for production and manufacturing.

③ Aluminum has good ductility, and can be made into light alloy with many metal elements, with superior materials.

④ Aluminum is a kind of benign recyclable metal material with stable chemical properties, nonmagnetic and recyclable.

These are the advantages of aluminum, so at present, more high-altitude fall arresters use aluminum shells, which provides better help for its production process and application environment.
