If they were placed several years ago, the engineering firms should be a group of people who are brilliant, they have a variety of customer resources, and the geographical relationship of the regional market. However, with the intensification of industrial squeeze, the voice of security project developers has clearly begun to weaken, then, what are the reasons for weakening the weight of the industry chain?
1, Party A and factory direct contact
As we all know, manufacturers face the users of Party A directly and assign the brand directly to Party A to obtain obvious benefits, and to make the price of the product transparent. Moreover, some large-scale equipment manufacturers have even directly involved in the project tendering and bidding process, making the project business transparent.
2, "price war" between peers
"Price war", no matter what the same industry, does not want the price war between peers, but some engineering companies in the face of the market squeeze, do not hesitate to push down the price, even when the bid price is 50% of the bid price, In this case, in order to earn money, they had to cut corners and cut down on the quality of the project.
3, the project business itself
The enterprise itself has not adapted to the needs of modernization and has no core technology. The content of the solution is simply listed and piled up. The homogeneity is serious.
4. Who will pay for the wages?
In engineering, it seems that defaulting on wages has become a normal thing. The equipment supplier finds the engineering firm to ask for money, the engineering firm asks the user for money, if the fund cannot be quickly replenished, the worker strikes, the loss of the technician and the like occur from time to time, and the integrator will only continue to complete the project with the debt.
The above several issues can be said to be the main problems faced by the development of engineering companies. A large number of equipment manufacturers established their own solution team and construction team, and directly docked with the user. In the face of these dilemmas, the contractor had to mock himself as a “water electricianâ€.
Throughout the security: security is so big, so small engineering business. The contractor, where do you go?
Alnico (AlNiCo) is the first developed a permanent magnet is made of aluminum, nickel, cobalt, iron and other trace metals composition of an alloy.According to different production process is divided into sintered Alnico (Sintered AlNiCo), and cast aluminum nickel and cobalt (Cast AlNiCo).Product shape of the round and square. Sintered products limited to the small size, their production out of rough tolerance is better than the rough cast product can be better workability.
Alnico alloys can be magnetised to produce strong magnetic fields and have a high coercivity (resistance to demagnetization), thus making strong permanent magnets. Of the more commonly available magnets, only rare-earth magnets such as neodymium and samarium-cobalt are stronger. Alnico Magnets produce magnetic field strength at their poles as high as 1500 gausses (0.15 teslas), or about 3000 times the strength of Earth's magnetic field. Some brands of alnico are isotropic and can be efficiently magnetized in any direction. Other types, such as Alnico 5 and alnico 8, are anisotropic, with each having a preferred direction of magnetization, or orientation. Anisotropic alloys generally have greater magnetic capacity in a preferred orientation than isotropic types. Alnico's remanence (Br) may exceed 12,000 G (1.2 T), its coercivity (Hc) can be up to 1000 oersteds (80 kA/m), its energy product ((BH)max) can be up to 5.5 MG·Oe (44 T·A/m). This means that alnico can produce a strong magnetic flux in closed magnetic circuits, but has relatively small resistance against demagnetization. The field strength at the poles of any permanent magnet depends very much on the shape and is usually well below the remanence strength of the material.
Alnico alloys have some of the highest Curie temperatures of any magnetic material, around 800 °C (1,470 °F), although the maximal working temperature is normally limited to around 538 °C (1,000 °F).[4] They are the only magnets that have useful magnetism even when heated red-hot.[5] This property, as well as its brittleness and high melting point, is the result of the strong tendency toward order due to intermetallic bonding between aluminium and other constituents. They are also one of the most stable magnets if they are handled properly. Alnico magnets are electrically conductive, unlike ceramic magnets.
Alnico magnets are widely used in industrial and consumer applications where strong permanent magnets are needed; examples are electric motors, electric guitar pickups, microphones, sensors, loudspeakers, magnetron tubes, and cow magnets. In many applications they are being superseded by rare-earth magnets, whose stronger fields (Br) and larger energy products (BHmax) allow smaller-size magnets to be used for a given application.
