Metal parts in products, we use copper, brass, and silver. Copper has a good ductility and electrical conductivity. Brass has good hardness which makes parts good mechanical utility. Silver has even better electrical conductivity than copper. We use copper for terminals, brass for mechanical purposing parts like the metal in rocker, silver on the contactors for best electrical conductivity. PC frame has very good insulative to protect user, also has good mechanical utility. It is dampproof, high temperature bearing (650℃). 1.2mm metal steel fixing base with power coating, it's very durable, excellent resistance to rust-proof, heatproof, fire resistance & insulation.
Each magnet's north and south pole are on opposite faces.
Excellent resistance to demagnetisation.
Coated with three layers of nickel, copper and nickel to reduce corrosion and provide a smooth finish.
PVC is non-toxic and taint free making this a suitable piping system for potable drinking water systems. Commonly used in Pumping Systems for Dairy Sheds, domestic and industrial plumbing, Water Filtration Systems, Wastewater Applications and Irrigation Systems.
The drill is made of carbon steel. Hardness of cutting edges 4554 HR?. It can be used with manual mechanical and electrical drills, as well as drilling machines. It is sharp on the side. The hexagonal tail prevents the drill from rotating in the chuck. This drill is intended for obtaining holes in softwood and hardwood with any type of fiber surface, glued plywood, chipboard.
It is designed optimally to be strong, light and safe for usage. Since the manholes are made with a complete understanding of the end-use, it assure these are easy to install, more accessible, higher strength, higher durability, easy handling and are cost-effective
