Precautions when using aluminum body steel mandrel blind rivets connection

- Feb 25, 2019-

When the aluminum body steel mandrel blind rivets  is selected, if the difference between the standard electrode potentials of the two mutual contact materials is large, such as the contact between the aluminum nail body and the steel plate or the contact between the aluminum nail body and the steel nail core, serious Electrochemical corrosion. To avoid this problem, use a suitable rivet coating or take appropriate measures of isolation between the connectors. In general, when the standard electrode potential difference between the two materials does not exceed 0.5V, it can be safely contacted.

In some parts related to the safety of the operation of the product, such as parts of products such as engines, motors or gas turbines, or short-circuiting of electrical products, which may cause serious accidents, if the individual parts of the aluminum body blind hole rivets are damaged, This type of rivet connection should not be used if the residue may fall into the running mechanism.

When the aluminum body steel mandrel blind rivets  is riveted, the rivet is first inserted into the hole of the connected piece, and then the nail core protruding the rivet body head is hit into the rivet body until it is flush with the top surface of the rivet body. At this time, the end of the rivet body is expanded to form an aluminum body steel core blind hole rivet. This connection enables quick and efficient installation, is extremely easy to install, requires no special installation tools, and is extremely inexpensive to install.
