Abstract

The invention discloses a special silver-free welding rod. The special silver-free welding rod comprises, by weight, 50-70% of Cu, 10-40% of Zn, 1-10% of Sn and 1-10% of rare metal alloy. The special silver-free welding rod is simple in component and low in preparing cost, a Bondi pipe is welded, the drill rod penetrating rate is high, the infiltration capacity is large, the strength and the air tightness are good, and the Bondi pipe can replace silver solder.

Description

Extraordinary without silver solder
Technical field
The present invention relates to technical field of soldering materials, be specifically related to a kind of extraordinary without silver solder.
Background technology
Along with the development of China's refrigeration cause, current condenser and evaporimeter output also increasing, the pipeline copper pipe of two gas, aluminum pipe, the weld Problems existing of iron pipe also highlights out, and by analysis and market survey, problem is wherein as follows:
1) because decades used by two organ pipe road welding materials, the old high silver products before a lot of manufacturer still continues to use, such as modal 45 silver medals, 35 silver medals, the material of 25 silver medals, silver is noble metal, material cost along with market one tunnel high, cost pressure strengthens suddenly; Although some producer has changed the product of lower silver now, but because noble silver is in composition, price is in increasingly competitive today, and advantage is little.
2) mostly the low silver products of present stage is the material containing cadmium, because cadmium can evaporate in welding production, produce poisonous cadmium vapor, have larger harm to human body, especially outlet or the industry relevant with food, their product used forbids having this kind of heavy metal of cadmium to exist, abroad, the all one-tenth accessories of this block of freezing are all requirement ROSH, and being the route of solder industry without cadmium, is also the route that industrial soldering must be walked.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of safety, environmental protection special type without silver solder.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of extraordinary without silver solder, be made up of the component of following mass percent:
Cu 50-70%
Zn 10-40%
Sn 1-10%
Rare metal alloy 1-10%.
The better quality percentage of each component is:
Cu 60%
Zn 35%
Sn 3%
Rare metal alloy 2%.
The invention has the beneficial effects as follows: present component is simple, and preparation cost is low, welding Bundy tube, the saturating rate of pricker is good, and infiltration capacity is large, and intensity is good, and air-tightness is good, can substitute containing silver solder.
Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with specific embodiment, setting forth the present invention further.
Embodiment 1
A kind of extraordinary without silver solder, be made up of the component of following mass percent:
Cu 60%
Zn 35%
Sn 3%
Rare metal alloy 2%.
Embodiment 2
A kind of extraordinary without silver solder, be made up of the component of following mass percent:
Cu 50%
Zn 40%
Sn 5%
Rare metal alloy 5%.
Welding rod associated technical parameters of the present invention is as follows:
Solidus: 887 degrees Celsius.
Liquidus curve: 903 degrees Celsius
Permeability: 4.07mm-5.23mm(is socketed welding)
Weld strength: 280MPa.
Extraordinary without silver solder, welding Bundy tube, the saturating rate of pricker is good, and infiltration capacity is large, and intensity is good, and air-tightness is good, can substitute containing silver solder.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
