Main Listing:

Studs manufactured by Erfolg are mechanical fasteners which are threaded on one or
both ends. One end is secured to an object. The other end is used typically with a
nut. Studs are available in both English and Metric threads. Metallic studs are made
from aluminum, brass, bronze, silicon bronze, copper, steel, titanium, and
specialized or proprietary materials. Non-metallic studs are made of plastic, fiber-
reinforced plastic, nylon, polyvinyl chloride (PVC), polyvinylidene fluoride (PVDF),
polytetrafluoroethylene (PTFE), and synthetic rubber. Studs can be anodized, coated
with phosphate or black oxide, chrome galvanized, or plated with gold, nickel,
silver, tin, zinc, or zinc chromate.

Selecting metal studs requires an analysis of material specifications. Aluminum is
malleable, ductile, light, and trivalent with good electrical and thermal
conductivity, high reflectivity, and resistance to oxidation. Brass has good
strength, excellent high temperature ductility and reasonable cold ductility, good
conductivity, excellent corrosion resistance, good bearing properties and low
magnetic permeability. Bronze is a metal composed of copper as the main alloying
metal and one or more other metals, such as tin, zinc, or phosphorus. Silicon bronze
is a typical stud alloy. Copper is a reddish metallic element that is ductile and
malleable and is one of the best conductors of heat and electricity. Copper also
exhibits good corrosion resistance. Titanium is hard, light, strong and corrosion-
resistant. Titanium studs are used widely in the aerospace industry and in medical
applications, such as replacement joints.
