Differences between taps made of different materials
1. Plastic tap: disadvantages: insufficient hardness, a short servicelife and poor appearances; advantages: high toughness, no rustiness, a low price and easy replacement
2.Coated cast iron tap: disadvantages: low toughness, tendency of rusting, and good appearances; advantage: high hardness. Common materials: zinc-plated cast iron, chrome-plated cast iron, copper-plated cast iron (only red copper).
3.rass tap: disadvantage: lower hardness than cast iron; advantages: high toughness and no rustiness. Common materials: brass and brass alloys.
4.Stainless steel tap: disadvantage: a high price; advantages: high strength, high toughness, no rustiness and good appearances.
Disadvantages and advantages of the brass tap
A copper tap refers to the tap made mainly of metal copper, and most copper taps sold on the market nowadays are brass taps. Is copper tap a good tap? What disadvantages and advantages does a copper tap have? Let’s take a look with Yijin Hardware.
1.As one of essential microelements for the human body and an important constituent part of enzyme and protein, copper can promote the human body’s metabolism and improve its functions. Copper can also effectively suppress the growth of bacteria and microorganisms, so as to keep water clean and hygeian. The copper tap features very high impenetrability against dust, grease, bacteria and virus which would lead to water contamination. Therefore, the use of copper taps has a positive effect to human health.
2.Copper features good corrosion resistance and rusting resistance. With advantages like good appearances and duration, easy installation, safety and fire prevention, and hygiene and health, the copper pipe has obviously higher cost performance than the zinc-plated copper pipe and the plastic pipe. The cupric ion has a powerful sterilization function to prevent the prevalence of some common livestock diseases. As an essential micronutrient to human health, copper has a great influence on the blood, nervous centralis and immune system, hair, skin and bone tissues as well as internal organs like brain, liver and heart for their development and functions.
Important knowledge about copper surface treatment
Copper is a kind of solid steel with purple appearances. Because copper has extremely active chemical properties, its inevitable contact with oxygen and fine dusts in the air during production, use and storage easily causes the copper surfaces to oxidate and change color. In the case of serious corrosion, copper parts are affected even for their appearances and electric conductivity. Copper’s symbol of element is Cu. By alloy composition, copper can be divided into pure copper, brass, white brass, and bronze. As a golden copper alloy with zinc as its main adding element, brass is commonly used for copper jewelries, building hardware, heat-exchanging tubes, pumps, and power cylinders.
Because of active chemical properties, copper has a disadvantage of rapid color change after oxidation. The production cost would increase without a good protection method, so a proper copper protection method should be selected: passivating treatment. The passivating treatment refers to that copper has a significantly decreased corrosion speed after treated by the oxidant medium. So how to deal with the oxidated copper with color change? Chemical or physical cleaning and polishing is required for improved copper surface evenness and brightness to restore its surface gloss.
Both of these two precision CNC machined components are very difficult to machine. First, they are both small and precision products, so it is difficult for a manufacturer with insufficient capabilities. Second, these two products are complicated in terms of both internal and external structures. If you choose Yijin Hardware, you don’t have to worry about this at all. With a history of 20 years in the precision custom CNC machining industry, Yijin Hardware has hundreds of advanced machining devices and experienced operators and engineers who can work independently.
