1. Zinc alloy is an alloy composed of zinc and other elements.

2. Titanium alloy is an alloy composed of titanium and other elements.

Second, the performance is different.

1, zinc alloy: relatively heavy. Good casting performance, can die-cast precision parts with complex shape and thin wall, and the casting surface is smooth. Surface treatment can be carried out: electroplating, spraying, painting, polishing, grinding and so on. When melting and die casting, it does not absorb iron, corrode and form, and does not stick to the mold. It has good mechanical properties and wear resistance at room temperature. Low melting point, melting at 385℃, easy to die-cast.

2. Titanium alloy: high strength, some high strength titanium alloys exceed the strength of many alloy structural steels. High thermal strength, the working temperature of titanium alloy can reach 500℃, while that of aluminum alloy is below 200℃. Good corrosion resistance, titanium alloy works in humid atmosphere and seawater medium, and its corrosion resistance is far superior to that of stainless steel. Good low temperature performance, and can still maintain its mechanical properties at low temperature and ultra-low temperature. Titanium with high chemical activity has high chemical activity and reacts strongly with O, N, H, CO, CO2, water vapor, ammonia and so on in the atmosphere. Low thermal conductivity and elasticity.

Third, the application is different.

1, zinc alloy is mainly used to make doors, windows and auto parts.

2. Titanium alloys are mainly used to manufacture compressor parts of aircraft engines, followed by structural parts of rockets, missiles and high-speed aircraft.

Extended data:

First, new titanium alloys.

1, high temperature titanium alloy

The first high-temperature titanium alloy successfully developed in the world is Ti-6Al-4V, and its service temperature is 300-350℃. Subsequently, alloys such as IMI550 and BT3- 1 with service temperature of 400℃ and alloys such as IMI679, IMI685, Ti-6246 and Ti-6242 with service temperature of 450~500℃ were successively developed.

2. Titanium aluminum compounds

Compared with general titanium alloys, the biggest advantages of Ti-Al compounds as sodium-based Ti3Al(α2) and TiAl(γ) intermetallic compounds are good high-temperature performance (the highest service temperatures are 8 16 and 982℃ respectively), strong oxidation resistance, good creep resistance and light weight (the density is only12 of nickel-based superalloy), which makes them become.

3, high strength and toughness beta type

β titanium alloy has good cold and hot workability, is easy to forge, can be rolled and welded, and can obtain high mechanical properties, good environmental resistance and good matching of strength and fracture toughness through solution aging treatment.

Second, the new zinc alloy security window

The product characteristics of traditional stainless steel have begun to expose its disadvantages, and its quality commitment has also begun to be questioned. Its channel price system has been in a relatively transparent state. Jinsheng zinc alloy color steel protective window absorbs the advantages of existing doors and windows, becomes a new product with unique functions and its own characteristics, and is the third generation protective window.

Security window, zinc alloy color steel, is made of the same material as outdoor facilities such as highway guardrail and high-voltage electric tower. High strength, beautiful appearance, bright color, high quality and low price are the best substitutes for stainless steel protective nets.
