Also many things were done with stone tools. And for fine work they probably used meteoric iron.
Or not as the case maybe.
This talk about saw cuts in rocks = aliens is getting ridiculous again. Why would aliens need saws of any description? And just how many rocks with saw marks are there? And where is the evidence for perfectly straight sawed finished items?
Now, in regard to the metals they had:
Pre Incan Iron mine was found:

And in a previous post Ive made, wiki stated the copper used wasnt 'just' copper, but an alloy;
Wiki:
"Notable features at Pumapunku are I-shaped architectural cramps,
which are composed of a unique copper-arsenic-nickel bronze alloy. These I-shaped cramps were also used on a section of canal found at the base of the Akapana pyramid at Tiwanaku. These cramps were used to hold the blocks comprising the walls and bottom of stone-lined canals that drain sunken courts. I-cramps of unknown composition were used to hold together the massive slabs that formed Pumapunku's four large platforms. In the south canal of the Pumapunku, the I-shaped cramps were cast in place. In sharp contrast, the cramps used at the Akapana canal were fashioned by the cold hammering of copper-arsenic-nickel bronze ingots.[9][12]
The unique copper-arsenic-nickel bronze alloy is also found in metal artifacts within the region between Tiwanaku and San Pedro de Atacama during the late Middle Horizon around 600–900.

So this copper-arsenic-nickel bronze alloy, is not entirely dis-similar to what is known as Cupronickel, depending on the recipe used
But for anyone to know for sure - a whole load of tools need to be found and analysed, as obviously any such tools and weapons evolve over time with continued study and usage. But one thing is clear, these were not a people unfamiliar with working metals:
"Even though the Inca Empire contained a lot of precious metals, the Incans did not value their metal as much as fine cloth[citation needed]. The Incans adopted much of their metal-working characteristics from the metalwork of Chimu.
Because of their expertise in metalworking, after the fall of Chimu many metalworkers were taken back to the capital city of Cuzco to continue their metalworking for the emperor. Copper, tin, gold, and silver were all obtained from mines or washed from the river gravels. These metals would then be handed over to metallurgists. Because the Inca had a system that emphasized political and religious organization, there were many specialized artisans like metallurgists. There were also specialized weavers, cloth makers, pottery makers, and many more.
Both copper and bronze would be used for basic farming tools or weapons. Some of the common bronze and copper pieces found in the Incan empire
included sharp sticks for digging, club-heads, knives with curved blades, axes, chisels, needles and pins. All of these items would be forged by a metallurgist and then spread throughout the empire.
The Incans reserved their more precious metals for ornaments and decorations. Gold and silver were common themes throughout the palaces of Incan emperors. It was said that the walls and thrones were covered with gold and that the emperor dined on gold and silver service. These golden plated services would often be inlaid with llamas, butterflies or other creatures. Even beyond the gold and decoration of the emperor’s palace were the ornaments that decorated all of the temples throughout the empire. The temples of the Incans were strewn with sacred and highly precious objects. Headdresses, crowns, ceremonial knives, cups and a lot of ceremonial clothing were all inlaid with gold or silver.
