Basic information thorium tungsten needle

Thorium tungsten carbide inserts needle is our cutting-edge R & D and manufacturing ← → Look for cutting-edge brand licensing [] Beware of fake aluminum welding, aluminum welding wire, aluminum solder, the basic sizes: Electrode diameter 0.5-5.0mm, length 350-1000mm, also according to demands of users.
ALUMINUM electrode grade condensed list:
  L109 (model E1100) is a pure aluminum core for the welding, coating for the base model of the aluminum electrode. For welding aluminum, aluminum containers.
  L209 (model E4043) is Al-Si alloy welding core, coating for the base type of aluminum alloys its greater versatility, good performance is characterized by thermal cracking of weld metal has a certain mechanical strength. For welding aluminum, aluminum-silicon alloy castings, wrought aluminum, hard aluminum alloy and other general. But not welded aluminum-magnesium alloy.
  L309 (model E3003) based on aluminum-manganese alloy welding core, coating for the base type of aluminum alloys, which is characterized by a high weld strength and corrosion resistance of aluminum similar. For welding aluminum-manganese alloys, aluminum and other aluminum welding.
Two kinds of low-temperature aluminum electrode (cold aluminum wire) to provide customer choice!
A necessity dip solder, melting point about 450 ℃:
  This product is a welded aluminum tank, aluminum air conditioning, private, low temperature. Good leveling, filling the gap ability. Welding thin pieces of advantage is very prominent. Suitable for various flame welding. Such as gasoline, liquefied petroleum gas, oxyacetylene and so on. Its excellent crack resistance and high tensile strength.
Weldable aluminum raw, cooked aluminum, aluminum alloy. Wire is 2.0mm × 900mm solder powder of 500g per bag.
Steps: 1 Heat welding rod, 2 dip solder powder (not mixed with water), 3 Preheat the end pieces, four test welding (welding rod is welded in place paddling, as seen in four solder powder like water drips, the bottom piece washed, then the rod will melt like water to weld it.
Two kinds without dip solder, melting point about 350 ℃:
  This product is a high-performance green copper and aluminum, aluminum and aluminum brazing material, the product in the electrical, transformer, refrigeration, sanitary ware, hardware and other industries widely used. Aluminum and aluminum alloy brazing growing demand. The melting point of aluminum is 660 degrees Celsius. And aluminum, as it contains different alloying elements, the melting point of his 482 degrees Celsius to 660 degrees Celsius. Aluminum and heated from room temperature to the melted state, there is no color change, determine the base material temperature when welding is difficult, too easy to burn or melt the base material.
