The solders that we have found to answer our purpose best are composed of the following elements.
The best and most practical thing to do under the circumstances, it seemed, was to carefully revise the different cost prices of the alloys and solders specified in Chapters VI.
The best solders we have found to be those mixed with a little zinc.
Table of Revised and Up-to-date Cost Prices of the Different Solders in Chapter VII.
The various degrees of fusibility of the several solders are occasioned by the different proportions of the component parts of the elements which enter into their existence.
The water of Comfrey solders broken bones, being drank, helps ruptures, outwardly it stops the bleeding of wounds, they being washed with it.
Solders must be, therefore, selected in reference to their appropriate metals.
Bismuth alloys are employed in automatic fire sprinklers, in safety plugs for boilers, in electric fuses, in solders and dental amalgams, and in some type and bearing metals.
During the war the critical scarcity of tin led to experiments in the substitution of cadmium for tin in solders and anti-friction metals.
These solders are all fusible at a low temperature, and they do not, as a result, have great strength.
The hard solders are used for uniting brass, bronze, copper, and iron.
Other hardsolders are alloyed as follows: brass, 4 parts; and zinc, 5 parts.
Harder solders to be used with a blowpipe may be made with alloys of zinc, tin, and aluminum.
This can be soldered with any of the jeweler's solders of gold, silver, and zinc in the usual way.

Silver solders may, of course, be purchased at watchmakers' supply shops, and as thus obtained, are generally in thin sheet.
The hard solders are the spelter and the silver solders.

I shall show how I helped Mr. Solders out of his dilemma.
Now Mr. Solders is a thrifty man, so he naturally desired to make the two cisterns of such dimensions that the smallest possible quantity of metal should be required.
I persuaded Mrs. Solders to explain matters to me.
Ordinary soft solders are lead-tin alloys, and the larger the proportion of lead the commoner is the solder said to be.
Almost as soon as aluminium was prepared on a large scale, it was discovered that the ordinary solders and fluxes did not answer with it.
The table on the opposite page gives the fluxes and the compositions of soft solders suited to a number of different metals.
Aluminium does not alloy readily with solders at temperatures as low as other metals require; and, secondly, aluminium alloys with lead solders only with great difficulty, and with but a small proportion of lead at that.
For hard-soldering a gold ring without discolouring it, use solders containing gold, the precious metal in the solder being afterwards laid bare by a process of annealing and pickling.
In making any of the above solders the brass and silver should be melted together, and care should be taken to see that the metal is clean beforehand.
Inasmuch as zinc alloys with aluminium more readily than does any of the common metals, solders that will readily “tin” aluminium generally contain zinc in varying proportions.
These should make ideal solders for beginner’s use, as the chances of burning the work, even thin brass, are almost nil.
The soldersare prepared to suit the quality of the gold to be soldered, so that they may “colour” well and thus hide the joint.
On board the vessels they embarked the sick, and those above forty years of age, with the boys and women, and all the baggage which the solders were not absolutely forced to take for their own use.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "solders" in a variety of sentences. We hope that you will now be able to make sentences using this word.
