For bonding metals is not suitable for every glue. Therefore, carefully read the supplied manual or consult the dealer upon purchase. If, for example, you must glue metal to rubber, look for adhesive that is suitable to both those materials, and not only to one of them.
Besides, the metal metalfrom different. If two raw aluminum parts to glue together is not too difficult, then the steel will have little trouble.
For gluing most metals better to buy two-component adhesive of epoxy resin, and stainless steel should choose the glue with methyl acrylate.
Uniform instructions for bonding metals no. Some better glue dot method, for some you have to squeeze out of the tube bead, and large planes there is a special glue that you need to smear a thin layer on the bonding surfaces.
But in all cases the metal before work will have to free from dirt and grease. This will significantly increase the quality of gluing and prolong its service life.
Cleaning details fine sandpaper, apply glue on them, as it is written in the instructions, secure them to each other and leave for some time for the adhesive.
Some glues hold much better if you give them the so-called "hot setting". Just put the glued parts on a baking sheet the oven and leave them for 3 hours at 90°C. But it can be done with the glue, the instructions which indicated good tolerance of high temperatures.
Advice 2 : How to glue metal to metal
In everyday life we often face the need to glue two metal object. Second adhesive, which in recent times has become popular to glue everything, in this case not do. Contact a proven and reliable method of gluing pieces of metals of different alloys.
First, you have to go to the store. Better not to waste time looking for the necessary funds in otetela economic or construction of goods, and immediately head to the auto parts store. This is where you can find two-component "cold welding", which is the best job of bonding metal objects. Choose a tool, set which includes two tubes: the active substance and the hardener. This may be the same Poxipol or other epoxy glues. In the same shop buy a small bottle of any solvent.
After returning home, degrease the bonding surface with a solvent to ensure the best contact. If the surface of one of the items have rust, clean it with emery paper or wire brush. Once all is ready for gluing, mix the active substance with the hardener in equal proportions, apply the entire mixture to the bonding surfaces and press them to each other. Curing time for most epoxy adhesives is between 5 and 15 minutes, so you should act quickly. Use glued objects to destination immediately after full cure.
"Cold welding" glues well not only metal but also plastic and wooden objects.
After the glue hardens, it can be treated with a file, sandpaper, angle grinder machine ("Bulgarian") and any other tools that can shape metal.
