Comparison of advantages and disadvantages between stainless steel smart lock and zinc alloy smart lock

at present, the materials used in smart locks on the market are roughly divided into two categories, one is zinc alloy smart locks, and the other is stainless steel smart locks. In general, many consumers are difficult to distinguish the differences, advantages and disadvantages between the two; At the same time, many smart lock enterprises are not sure what kind of smart lock consumers like

therefore, Mr. lock today specially summarizes for you the differences, advantages and disadvantages, and resolution methods between the stainless steel smart lock and the zinc alloy smart lock in reducing the energy consumption of 100 million tons of standard coal. What is the distance between the markings? Most of the distances given by different standards have a certain difference, which is beneficial to officials

1 the "28 law" of the smart lock industry

Italian economy 6 Displacement measurement range: 2% of the full scale ⑴ within the range of 00%, economist Pareto found that 20% of people in society occupy 80% of social wealth, that is, the distribution of wealth in the population is uneven. This is the famous "28 law"

whether the result is exactly 80% or 20%. Traditionally, the 28 law discusses 20% of the top, not 80% of the bottom. The 28 law, which is adopted by people, is a quantitative empirical method to measure the possible relationship between input and output

in addition to the "28 law" phenomenon, it also appears in the smart lock industry. But is this "28 law" different from Pareto's "28 law"? It refers to the market share here. Quoting Pareto's "28 law" is just an introduction

at present, the market share of zinc alloy smart locks is about 80%, and that of stainless steel smart locks is only about 20%. Due to cost and other reasons, stainless steel smart locks are mostly used in high-end places or places with high security requirements; Zinc alloy smart lock is usually more affordable due to its relatively low cost

why does the smart lock industry present such a "two eight law"? This also has to be analyzed from the advantages and disadvantages between the two and their respective characteristics

2 advantages and disadvantages of stainless steel intelligent lock

at present, stainless steel intelligent lock is mainly 304 stainless steel, which can be widely used in coastal, high cold, high temperature and other different areas

I. advantages of stainless steel intelligent lock. 1) It has strong corrosion resistance and can be widely used in coastal and tropical rainforest areas with high salinity and humidity: 2) it has the characteristics of heat resistance and low temperature intensity, and can be used in areas with severe cold, high temperature, or large temperature difference; 3) High strength, with fire prevention, drilling prevention, prying prevention, sawing prevention, impact prevention and other functions, long service life and high safety: 4) uniform texture, good density, no pores, sand holes, bright, uniform and delicate color, which can maintain the original appearance of the product for a long time

second, the disadvantages of stainless steel intelligent lock. 1) The cost of stainless steel smart lock is high, which is generally more than twice that of zinc alloy smart lock; 2) Stainless steel is hard and difficult to form, so the appearance and shape are too single and the selectivity is poor

3 advantages and disadvantages of zinc alloy smart lock

zinc alloy is an alloy based on zinc and added with its VOC: volatile organic compounds and other elements. Commonly added alloy elements include aluminum, copper, magnesium, cadmium, lead, titanium, etc. Zinc alloy is the most widely used material in the intelligent lock industry at present. What are its advantages and disadvantages

I. advantages of zinc alloy intelligent lock. 1) Good casting performance, can die cast precision parts with complex shape and thin wall, with smooth casting surface, diverse patterns and high selectivity; 2) It can be electroplated, sprayed, painted and other surface treatments, with diversified colors; 3) Good mechanical properties and wear resistance at room temperature; 4) Low melting point, melting at 385 ℃, easy to die cast, many styles and shapes: 5) relatively low cost, slightly lower price than stainless steel smart lock

second, the disadvantages of zinc alloy intelligent lock. 1) Poor corrosion resistance. When the impurity elements lead, cadmium and tin in the alloy composition exceed the standard, the castings will be aged and deformed, which will show as volume expansion, significant decline in mechanical properties, especially plasticity, and even rupture for a long time. The solubility of lead, tin and cadmium in zinc alloy is very small, so they concentrate on the grain boundary and become the cathode. The aluminum rich solid solution becomes the anode, which promotes intergranular electrochemical corrosion in the presence of water vapor (electrolyte). Die castings are aged due to intergranular corrosion; 2) Zinc alloy die castings should not be used in the working environment of high temperature and low temperature (below 0 ℃). Zinc alloy has good mechanical properties at room temperature. However, the tensile strength at high temperature and impact properties at low temperature decreased significantly

4 how to distinguish the differences between the two

it is difficult for ordinary consumers and many practitioners in the smart lock industry to distinguish the differences between stainless steel smart locks and zinc alloy smart locks. Here, Mr. lock summarized three methods of "one look, two strokes and three numbers" for you, hoping to help you

take a look. Due to the relatively difficult forming of stainless steel, the appearance is relatively simple without too many complex patterns. The surface is directly brushed, and there are no electroplated bubbles and particles; Due to its strong plasticity, the zinc alloy intelligent lock has many styles, beautiful patterns and patterns, and obvious electroplated bubbles or particles on the surface; Compared with zinc alloy lock, stainless steel lock has natural luster, delicate and delicate texture, and warm texture, presenting gorgeous texture under the light

two strokes. A hard object can be used to scratch on the front or back panel of the lock. A stainless steel smart lock with a hard texture and a unified or similar color inside and outside the scratch; Those with soft texture and silver scratches are zinc alloy smart locks

three numbers. Because the stainless steel smart lock is hard, there is no positioning fulcrum on the back of the panel; Both the zinc alloy smart lock panel and the smart lock need to be cast, and the material is soft, so the back of the panel needs a positioning support point, which is distributed around and in the center of the panel respectively

5 conclusion:

from the above analysis, it can be seen that stainless steel smart lock and zinc alloy smart lock have their own advantages and disadvantages. At present, the use environment of stainless steel smart lock is better than that of zinc alloy smart lock, and the security is higher; The zinc alloy intelligent lock has novel styles and diverse patterns, which can meet the needs of different consumers. But in the view of lock Jun, with the progress of technology, the difference between the two will gradually reduce, and the gap will gradually narrow
