Q:Can we import scrap tanks and other scrap metals from Russia?

Weapons can not be imported waste weapons, dismantling can be imported, of course, there are many quite complicated documents and approval, inspection and other processes. Strict requirements, of course, this kind of examination and approval is two-way, that is, whether Russia or China should check and approval, so tedious headache. And there's a big problem. That's tank metal. Many are special metals. There are many kinds of alloys inside. Therefore, after dismantling, the cost of separation is quite large, which involves the cost of the problem.

Q:What is the sign of PD? What are the signs of other precious metals?

The United States provides purity to called Pt, must contain at least 50% platinum, platinum and platinum content. A total of 95% more than 95% purity can play Pt mark. The platinum content between 75%-95% jewelry, must also be on the platinum metal jewelry mark. Platinum content between 50%-75%, will the name must be contained in a platinum group metal and its content.

Q:Ordinary AB glue, can stick metallic objects?

Can sticky metal AB glue, such as HY-106 AB is for the deployment of metal.

Q:What metal does nonmagnetic metal have?

All metals except iron, cobalt, and nickel

Q:What does "productive scrap metal recycling" mean?

Productive scrap metal recycling refers to the recycling of metal materials and metal products used in construction, railways, communications, power, water conservancy, oil fields, national defense and other production areas, and has lost its original use value.

Q:Will the metal ions in the layered composite metal oxides be replaced by other ions?

First of all, metal oxides are active, metal oxides are ionic compounds, and active metal oxides are active metals and active nonmetallic compounds

Q:Are iron and steel nonferrous metals?

Iron, manganese and chromium are ferrous metals, and other metals are nonferrous metals.More importantly, both non-ferrous metals and ferrous metals are within the limits of purity. Steel is an alloy of carbon and iron, a mixture, an alloy, and not a metal.What we commonly call iron and steel is steel. It is not a non-ferrous metal.

Q:What does "active metal" mean?

Second, understand the lively nature of metals:1. the intensity of the reaction with oxygen.2. the intensity of the reaction with the acid.3. is the metal able to displace other metals from the solution of their compounds?.4. whether it can displace hydrochloric acid, hydrogen in dilute sulfuric acid.The more active metals themselves tend to lose electrons and undergo oxidation reactions, and their potential is lower.

Q:What is a metal without magnetism?

This is not necessarily, is not a single kind of metal, still can not say.

Q:What metal is black?

The name "ferrous metals" and "nonferrous metals" is often misunderstood. Black metals must be black, but they are not. There are only three ferrous metals: iron, manganese and chromium. And neither of them three is black! Pure iron is silvery white; manganese is silvery white; chromium is grey. Because the surface is often rusty iron, a mixture of magnetite and brown covered with a layer of black ferric oxide, is looked black. So people call it "black metal"". Often referred to as "black metallurgical industry", mainly refers to the iron and steel industry. Because the most common alloy steel is a steel and chromium steel, so, people manganese and chromium can be considered as a "black metal".
