You must space them with another material so you do not get electrolysis
that's all put something like electrical tape between the two pieces of copper.
copper is higher in galvanic series than steel.hence when steel bolt is attached to copper equipment the copper being higher in galvanic series acts as anode getting corroded and steel being lees in galvanic series acts as cathode getting protected. copper equipment gets corroded when steel bolt is attached to it.
Yes
I'm pretty sure there is a copper washer on both sides of the hose fitting.The screw you refer to is the hollow bolt with a small hole in the shank,called a banjo bolt.
Copper is an excellent conductor of electricity, and so can safely conduct away the charge of a lighning bolt without heating up and creating a fire hazard. The only better conductor is silver, which is too expensive for such a use.
Hold the fitting still with a wrench while you turn the banjo bolt counter clockwise. You will need new copper washers when you reinstall, and the brakeline will also need to be bled.
The brake hose is connected to the caliper with a special hollow bolt. There are also two copper washers used, along with rings on the bolt and the parts, to seal the brake fluid in a high pressure fitting.
2 copper crush washers one under the head ...one after the bolt passes thru the line block.
look under right side of engine.It is hard to get at but use a 17mm wrench to undo the bolts on eather side of the fuel filter.Now undo the two 10mm or 12mm bolts that hold the filter in place and remove it.Be sure to replace the copper washers on the two 17mm bolts.There are two of them on each bolt.One goes on the filter side and the other goes on the bolt side.It is better to put one copper washer on the bolt first then put the fuel hose on the bolt then the other washer.Screw the bolt into the filter and tighten.(ps if you drop the front bolt and can't find it it's no doubt between the engine and starter.
Yes. The shears of the cutter will have a fairly unique pattern left from the grinding, which will transfer to whatever that's cut with them. But the shears themselves are too hard to take any impression from the copper. There might be a degree of metallic smearing, but that's all.
The building tools of nuts and bolts can be made out of lead. Some other properties that might be used are, nickel, titanium and copper or a mixture of these elements.
It has a check screw on the right side of the engine...forward of the clutch cover. Its easy to spot because it has a copper washer. Remove the 8mm bolt and fill the crank case till oil comes out of the bolt hole...then you know your good.
Copper contain copper !!
