Platings & Finishes
|
|
Brass Plated
|
Dull to bright yellow
decorative appearance. Excellent rust protection.
|
|
Galvanized
|
Galvanizing is the
process of coating iron or steel with zinc - originally
by using direct current and a zinc anode. Increased rust
resistance over typical zinc plating. |
|
Nickel Plated
|
Nickel has more of a
silver color to it than zinc and has similar corrosion
resistant characteristics. It is the standard finish of
cap nuts and countersunk finishing washers. |
|
Zinc Plated
|
Electro-galvanizing is
the process of coating metal with zinc by
electrodeposition. Minimal rust resistance. |
|
Materials
|
|
Alloy
|
Alloy steel is a steel
containing elements other than carbon which have been
added to obtain definite mechanical or physical
properties, such as higher strength at elevated
temperatures, toughness, etc. |
|
Aluminum
|
The most abundant metal
in the earth, aluminum is blueish and silvery-white,
very light, malleable, and ductile with high heat and
electrical conductivity. It is non-magnetic and one-third
the weight of steel with good corrosion resistance
against certain chemicals and acids but weak resistance
against other elements such as sea water. |
|
Nickel
|
A metal added to 300
series stainless to provide corrosion resistance,
increased strength in both high and low temperatures,
and increased toughness in low temperatures. Nickel
lowers the effects of work hardening, thus reducing
traces of magnetism caused by cold forming and making
material flow more freely in manufacturing. |
|
Nylon
|
Strength properties,
particularly its ability to be torqued are good. It is
tough, has good resistance to creep and fatigue, and it
has excellent elasticity and resiliency to rebound to
its original shape following deformation. Nylon is
reasonably impervious to corrosive attack by most
chemical solvents and it is self-extinguishing if set
afire. |
|
Solid Brass
|
The most common alloy of
copper, brass is basically two-thirds copper, one-third
zinc. It is non-magnetic with good strength and
toughness, high electrical conductivity, and an
attractive lustrous finish. It has good corrosion
resistance but not in salt water. Brass is commonly used
by the electrical and communications industries,
builders hardware, and some marine applications.
|
|
Stainless Steel
|
A highly corrosive
resistant fastener, commonly used in wet environments.
|
|
Steel
|
Low carbon or heat
treated. |
