Ana amfani da guduɗan sosai ga badarorin connector, kayayyakin, aljafari, da pins.

S tainless steel

(1) Stainless steel ya fitowa wajen yankin da ke bukata tsaron abubuwan da ke cikin sannar connectors, kamar aljafari bênze;

(2) Tsarin tsabo mai zurfi, miton mai zurfi, da kyauyar dutsen dutsen. Ana amfani da stainless steel ga wasu abubuwan cimma na kayan connector, kamar shell bênze.

Stainless steel a halin general ana amfani dashi kamar abubuwan da ke furuci, abubuwan shell, ko abubuwan aljafari bênze.

A luminum alloy

(1) Alasika yana amfani da aluminum a cikin yanayin alloy, wanda ke kama da "Anticoorodal" alloy.

(2)Aluminum alloy ita ce saukiya a tsarin, tana da alamuwa mai kyau na karkashin, zaune, da alamar nuna (tame), tana da alamar sauƙi, da kuma alamar mai kyau na tsarin kayan aikin. A wasu lokuta ana amfani dashi a matsayin abubuwan daban (brass, stainless steel).

Za a iya amfani da aluminum alloy don ankyawan kayan aikin da kayan aikin connectors.
