What kind of flux do you use with lead-free solder?
Lead-free solder wires should contain at least 2\% flux by weight. Leaded solders are available with lower flux percentages as low as 1\% wt/wt; this low flux volume will not work well with lead-free.
What is petroleum-based flux used for?
Superior No. 130 is a petroleum-based plumbing flux paste that contains Zinc Chloride and Ammonium Chloride. The petroleum helps protect the solder joint against corrosive attack, and the flux’s paste form insures that the flux stays put until soldering.
Do you need to use flux with lead-free solder?
Lead-free solder generally requires a made-for-lead-free flux designed to be used under slightly higher temperatures. Liquid flux can greatly help with surface mount soldering and desoldering components, but the flux inside cored-solder should be sufficient for through hole components.
Is flux needed with flux core solder?
In these applications there is often no practical way to clean flux residue after soldering. If additional flux is needed during soldering it’s important to confirm the core flux type. Externally applied flux must be compatible with the flux cored composition you’re using.
What is lead free tinning flux used for?
It cleans, tins and fluxes most commonly soldered metals. 100\% lead free, No. 95 Tinning Flux is NSF listed for potable water applications. Its formula resists turning copper piping green and is excellent for large diameter copper pipe applications….Oatey® No. 95 Tinning Flux.

How strong is lead free solder?
217C
A: Lead-free solder has a higher melting point, which makes it harder to work with – it’s 217C for lead-free compared to 183C for lead alloys.
Can you tin a soldering iron with lead free solder?
The new lead free alloys are high in tin content and the tin will dissolve the plating on the solder iron tip and eventually eat through the tip. Using these pads will not cause any shock to the solder iron tip and should help increase the tip life.
When soldering Why should flux be used?
The main purpose of the flux is to prepare the metal surfaces for soldering by cleaning and removing any oxides and impurities. Oxides are formed when metal is exposed to air and may prevent the formation of good solder joints.
What is flux and solder paste used for?
Oatey® Flux and Solder Pastes facilitate the soldering process, removing dirt, surface oxidation and other impurities from the solder joint. All Oatey Fluxes and Pastes are lead free and come in a variety of formulas, including water soluble and tinning.
How much flux should be in a lead free solder wire?
Lead-free solder wires should contain at least 2\% flux by weight. Leaded solders are available with lower flux percentages as low as 1\% wt/wt; this low flux volume will not work well with lead-free.
What is the best way to solder lead free copper?
Of course you have to clean off both copper surfaces and use flux for lead free solder, but you probably already knew that. The other key is to apply the blue tip of the flame so that it is just in contact with the copper, and play it back and fourth between the pipe and the elbow, heating both evenly and quickly.
What is the difference between lead-free and lead based solder?
Lead based solder is still available in stores for other tasks, simply because it is a good solder that is very easy to use. But for plumbing, we have lead-free solder.
