قضيب لحام سبائك النحاس من شركة هاريرس أو فوس

Feature

• It mostly comprises copper (Cu) with a small amount of phosphorus (P) added.

It is typically used in hand-brazing works.

Perfect for brazing brass as well.

The weight of the Phos Copper brazing alloy welding rod is 0.8 ounces.

It naturally flows copper.

Copper brazing is an economical solution.

The alloy requires a precise joint tolerance of less than 0.005 in. (0.13 mm) since it flows swiftly at heating temperature.

Its dimensions are 2 x 0.2 x 14.5 inches in length, width, and height.

Brass is the external finish.

ال Harris-O Phos-Copper brazing alloy welding rod is an economical choice for connecting copper to copper uses. It flows rapidly at brazing temperatures and is self-fluxing. So copper junctions don’t need a separate brazing flux. Its quick flow characteristic does, however, mean that a successful braze requires tight fitting joints (less than 0.005 inches).

The two main parts of the welding rod made of copper-phosphorus brazing alloy are copper and phosphorus. The alloy exhibits a low melting point and good fluidity. It is rarely used for brazing ferrous metals because phosphorus is recognized to cause iron to become brittle.

Harris-O Phos-Copper brazing alloy welding rod is an affordable and efficient option for plumbers, refrigeration experts, and DIY enthusiasts working on tight-fitting copper projects.  This article will cover all the details regarding phos-copper brazing alloy welding rods. So, let’s get started!

Working Principle

The idea behind brazing is to fuse two metals using a filler metal. A metal filler with a melting point of less than 450°C is used in soldering.

Copper makes up the majority of the rod and gives the brazed joint exceptional thermal and the ability to conduct electricity. In the majority of copper uses, phosphorus is a necessary component that removes the need for separate heating flux. Phosphorus and the copper oxide layer interact during brazing to produce a smooth surface for a solid bond.

الاستخدامات

The plumbing, air conditioning, and refrigeration industries can employ copper phosphorus brazing alloy. The following are a few of its applications.

Refrigeration

This copper-phosphorous alloy can be used to braze joints with large gaps and is utilized to braze brass and copper. It is extensively used in the refrigeration and air conditioning sectors.

لحام

Its low melting temperature and superior fluidity make this copper-phosphorous alloy ideal for welding copper to brass. It is also utilized in the sanitary ware and motor industries.

التدفئة والتهوية وتكييف الهواء

Applications for plumbing, refrigeration, and HVAC (heating, ventilation, and air conditioning) frequently require copper brazing rods. It is renowned for having outstanding durability, corrosion resistance, and heat conductivity. Copper brazing rod is a versatile option for brazing applications since it is compatible with a wide range of metals and is reasonably easy to use.

الايجابيات

• • Harris-O is less expensive than other brazing alloys.
  • In most copper applications, there is no need for a separate brazing flux, which simplifies the brazing process.
  • Its fast flow rate when melted allows for faster brazing times.
  • The superior electrical conductivity capabilities of copper phosphorus brazing alloy make it the perfect material for wiring applications requiring rapid and effective electricity transfer.

سلبيات

• For best performance, the quick flow requires exact joint fitting (less than 0.005 inches of clearance is desirable). Weak brazes can result from loose joints.
• It is not advised to braze steel or other ferrous metals using Harris-O.
• Joints exposed to sulfur or sulfur compounds in service can break down over time.

تغليف

The Harris-O Phos-Copper brazing alloy welding rod is a low-cost, easy-to-use solution for connecting copper and copper alloys. Its main advantages are its self-fluxing nature for most copper uses, quick heating times, and affordability. 

However, because the molten material flows so quickly, well-fitting joints are necessary for successful heating. It is not advised for use with ferrous metals or in situations where exposure to sulfur compounds can occur, even if it is perfect for plumbers, refrigeration technicians, and do-it-yourselfers working on copper projects. Alternative brazing solutions should be investigated for certain circumstances.
