1. bitcoin mining machine is a kind of computer used to earn bitcoin. This kind of computer generally has professional mining chips and works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server
mining is actually a competition of performance and equipment, and a competition of computing power among miners. Miners with more computing power are more likely to dig bitcoin. With the increase of computing power in the whole network, it is more and more difficult to dig bits with traditional devices (CPU, GPU). People have developed chips specially used for mining. Chip is the core part of mining machine. The process of chip operation will proce a lot of heat, in order to cool down, bitcoin miner is generally equipped with heat sink and fan

bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce
bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high
2. 1. Impurity content: TA1, TA2, TA3 increase in turn,
2. Mechanical strength: TA1, TA2, TA3 increase in turn,
3. Hardness: TA1, TA2, TA3 increase in turn,
4. Plastic toughness: TA1, TA2, TA3 decrease in turn
the strength of TC4 (Ti-6Al-4V) low temperature titanium alloy increases with the decrease of temperature, but the plasticity changes little. It can keep good ctility and toughness at - 196-253 ℃ and avoid metal cold brittleness. It is an ideal material for low temperature vessels, tanks and other equipment.
3. What kind of material do you want! What's the use? Sometimes pure titanium is more expensive than titanium alloy!
4. Ta1-a is pure titanium plate for plate heat exchanger, which is used for stamping plate of plate heat exchanger. TA1 is pure titanium plate.
5. Ta1-a is pure titanium plate for plate heat exchanger, which is used for stamping plate of plate heat exchanger. TA1 is pure titanium plate
6. There is no special difference in appearance, but the titanium content of their components is different. The titanium content of TA1 can reach about 99.5%, the titanium content of TC4 is less, TC4 is more difficult to process than TA1, and TA1 is softer
7. You said 7075 is aluminum alloy, TA1 is hard
8. Instrial pure titanium can be divided into TA1, TA2 and TA3 according to the impurity content. The interstitial impurity elements of these three kinds of instrial pure titanium increase graally, so the mechanical strength and hardness increase step by step, but the plasticity and toughness decrease accordingly. TA2 is commonly used in instry because of its moderate corrosion resistance and comprehensive mechanical properties. TA3 can be used when the requirements for wear resistance and strength are high. TA1 can be used when better molding performance is required. TA1, TA2 and TA3 in GB correspond to gr0, GR1 and Gr2 in UNS. The effect of TA1 and TA2 on iron content ω 095%, oxygen content ω 08%, hydrogen content ω 0009%, nitrogen content ω 0062%, it has good low temperature toughness and high low temperature strength, and can be used as low temperature structural materials below - 253 ℃.
9. Instrial pure titanium can be divided into TA1, TA2 and TA3 according to their impurity contents. The interstitial impurity elements of these three kinds of instrial pure titanium graally increase, so their mechanical strength and hardness graally increase, but their plasticity and toughness correspondingly decrease, Because of its moderate corrosion resistance and comprehensive mechanical properties, TA3 can be used when the requirements for wear resistance and strength are high. TA1 can be used when the requirements for better formability are good. TA1, TA2 and TA3 in the national standard correspond to gr0, GR1 and Gr2 in UNS ω 095%, oxygen content ω 08%, hydrogen content ω 0009%, nitrogen content ω 0062%, it has good low temperature toughness and high low temperature strength, and can be used as low temperature structural material below - 253 ℃
10. Is the grade of titanium, indicating the purity of the material and alloy ratio. TA1 is instrial pure titanium, which is characterized by relatively soft alloy, good ctility and bending resistance. TC4 is a titanium alloy Ti-6Al-4V with high strength and high temperature resistance
different brands have great differences in performance and usage.
